All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample
to make a statistical inference about the mean of the normally distributed population from which it was drawn?
Z S
ME= √n.

Answers

The margin of error is multiplied by √2.

Given that All else is equal if you cut the sample size in half and to make a statistical inference about the mean of the normally distributed population from which it was drawn ME=(z+s)/√n.

Margin of error (ME) from the mean can be calculated using the formula ME=(z+s)/√n where

z means it is the corresponding statistic of the given confidence level

s means it is the standard deviation of the sample (or of the population if it is known)

N is the sample size

As we know margin of error is proportional with inverse of √N,

If we will cut the sample size in half, the margin of error is multiplied by √2.

Hence, if sample size is cut in half then the margin of error when using the sample to make statistical inferences about the mean of the normally distributed population from which it was drawn is √2.

a physician orders 16 oz of 25% solution to be made from 10% and 50% stock solutions. how many ml of 50% solution are needed?

Answers

180ML of 50% solution are needed.

What is a solution?

Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution. An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution. To put it another way, a solution is a value or set of values (one for each unknown) that, when used to replace the unknowns, cause the equation to equal itself. Particularly but not exclusively for polynomial equations, the solution of an equation is frequently referred to as the equation's root.

EXPLANATION : To solve this question, we have initial stock solution of 10% and 50% concentration. We need to make final solution of 25% concentration of volume 16oz. [tex](1oz \approx 30ml)[/tex]

To find :- Volume of 50% required

Let us assume we require x oz volume of 50% stock Solution , Then volume of 10% stock added will be (16-x) oz.

Formula used here:-   C1V1 + C2V2 = C3V3

Where C1 = 50% = 0.5 , V1 = x oz    &   C2 = 10%= 0.1  , V2= 16-x oz

C3 = 25% = 0.25 ,  V3= 16oz

Putting values we have

(0.5*x) + (0.1(16-x)) = 16*0.25

0.5x + 1.6 - 0.1x = 4

x = 6

Hence Volume of 50% solution = x = 6 oz = 6*30 ml  = 180ml

The graph shows the relationship between the amount of time that a backpacker hikes and the distance traveled.

What does (5,6) represent?

What is the equation of the relationship?

Answers

a) The meaning of the point (t, s) = (5, 6) is that the backpacker travels a distance of 5 miles in 6 hours.

b) The equation of the relationship between the distance traveled by the backpacker and time taken is equal to s = (6 / 5) · t.

How to analyze linear equations

According to the image attached aside, we find that the distance traveled by the backpacker (s), in miles, is directly proportional to the time taken (t), in hours. In other words, we have the following relationship:

s ∝ t

s = k · t      (1)

Where k is the constant of proportionality, in miles per hour.

a) The meaning of the point (t, s) = (5, 6) is that the backpacker travels a distance of 5 miles in 6 hours.

b) To determine the equation of the relationship, we need to calculate the constant of proportionality. If we know that t = 5 h and s = 6 mi, then the equation of the relationship is:

The wind blew away 28 of your muffins. That was 7/10 of all of them! With how many did you start? As Equation Review

Answers

The total number of muffins were 40 and the equation which represnts the given scenarion is (7/10)x = 28.

Let the total number of muffins be x.

According to the given question.

The number of muffins which blew away by wind = 28

And 28 muffins are the 7/10 part of the total muffins.

Therefore, the linear equation in one variable which represents the above scenario is given by

(7/10)   ×  x = 28

⇒ 7x = 280        (multiplying both the sides by 10)

⇒ x = 280/7          (dividing both the sides by 7)

⇒ x = 40

Hence, the total number of muffins were 40 and the equation which represnts the given scenarion is (7/10)x = 28.

What are linear equations in two variables?

The equations with two variables where each variable has the largest exponent order of 1 having one, zero, or an infinite number of solutions, and are referred to as linear equations in two variables. A linear equation with two variables has the conventional form ax + by + c = 0, where x and y are the variables. Additionally, the answers can be expressed as ordered pairs, like (x, y).

What are forms of linear equations?

Linear equations have three main forms which are as follows:

Y=mx+b, where m is the line's slope and b is the y-intercept, is the formula for slope-intercept form.Ax+By=C is how standard form is expressed, with A, B, and C all being constants.(Y-Y1)=m(X-X1), where m is the slope and (X1, Y1) is a known point on the line, is how the point-slope form is expressed.

We will consider x on the graph to be years since 1986 and y on the graph to be the number of Moose.

We have two points on the graph:  (6, 5200) and (11, 7100)

Using the slope formula m = (y2 - y1)/(x2 - x1), we can find the slope of this line:

m = (y2 - y1)/(x2 - x1)                

m = (7100 - 5200)/(11 - 6)          

m =  1900/5                            

m = 380                                  

Now, that we have the slope of the line, we can use the point-slope formula (y - y1) = m(x - x1) to find the equation for the line.  Here, we're using the first point, but either point will produce the same answer.

(y - y1) = m(x - x1)                                    

y - 5200 = 380(x - 6)                            

y - 5200 = 380x - 2280                            

y - 5200 + 5200 = 380x - 2280 + 5200    

y = 380x + 2920                                    

Since the equation that is being sought is supposed to be in terms of P and t, We will replace y with P and x with t.

Hence, the equation will be P(t) = 380t + 2920.

Ok, since this is not a multiple choice question, I'll tell you how I would write it.

Step-by-step explanation:

It stopped snowing for 10 to 12 hours after the storm and then started snowing again. This is because you can see that the y value (amount of snow on the ground in inches) has no change between 10 to 12 hours after the storm began.

For the second part, Think of the independent variable as the cause(its value is independent of other variables) and the dependent variable as the effect, essentially the value that depends on changes in the independent variable. In this case it tells you that the perimeter of a square depends on the length, so that means that the length is independent and the perimeter of the square is dependent. So, the dependent variable is the perimeter, because the perimeter of a square depends on the length.

A function relating these variables is K(x) = y since the dependent variable (y) depends on the independent variable (x)

Now for the last part that says So K(5) = ___ meaning if 5 ___ I don't really understand what it is asking for, since K(x) = y then K(5) would equal whatever y is when x is 5, but k(5) could also equal 5k if we were just evaluating.

in a game of poker, what is the probability that a five-card hand will contain (a) a straight (five cards in unbroken numerical sequence)

Answers

The probability that a five-card hand will contain a straight = 5/1274

There are 52 cards in a deck from which each 13 cards are from 4 different suits (clubs, diamonds, spades and hearts) in a game of poker.

Each 13 cards from high to low are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King. So a straight of five cards, i.e., five cards in unbroken numerical sequence would be got only from 10 cards in a sequence.

So the possible ways to get a single straight five from all four suits = [tex]4^5[/tex]

Now as we doesn't need all 5 cards from a single suit, we can ignore 4 ways from the above number. i.e.,  [tex]4^5-4 = 1020[/tex] ways.

Hence the possible ways to get a straight five from 10 cards from all four suits = 10 x 1020 = 10200 ways

Total number of ways to select 5 cards from 52 cards = 52C5

Thus,

The probability that a five-card hand will contain a straight = 10200 / 52C5

                                                                                                  = 5/1274                        Learn more about probability at https://brainly.com/question/5858025

The predicted value for the given data is equal to 56.64 inches.The residual value for the given data is equal to 3.36 inches.

Given the following data:

Age in years of a child = 12 years.Height in inches = 60 inches.

What is a residual value?

A residual value can be defined as a difference between the measured (given or observed) value from a scatter plot and the predicted value from a scatter plot.

Mathematically, the residual value of a data set can be calculated by using this formula:

Residual value = given value - predicted value

Next, we would determine the predicted value by using the given regression equation as follows:

Hgt = 24 + 2.72(Age)

Hgt = 24 + 2.72(12)

Hgt = 24 + 32.64

Predicted value, Hgt = 56.64 inches.
