Consider the hospital from problem 4 of the homework that is using a statistical test to decide whether or not to accept future shipments of syringes from a supplier. The two errors the can make are to reject shipments that are actually acceptable and to accept shipments that do not meet the requirements. The hospital has decided that the error of accepting shipments that do not meet the requirements is substantially more important. They would like to ensure that they do not make this error even if that means increasing the chance that they reject acceptable shipments. When selecting their alpha (choosing between 0.01, 0.05 and 0.10) which alpha level provides the highest protection against this type of error?
a) alpha-0.01
b) alpha-o.05
c) alpha-0.10
Answer:
The correct option is a
Step-by-step explanation:
Gnerally assuming that
The null hypothesis is that the syringes from a supplier does not meet the requirement
and
The alternative hypothesis is that the syringes from a supplier meets the requirement
Now in order not to commit type I error which is wrongfully rejecting the null hypothesis then the level of significance need to be lower than the p-value (this is obtained from the z-table for any given z-score ) hence the suitable level of significance to achieve the hospitals aim is alpha-0.01

13 people take their driving test on the same day. 9 of them pass. What fraction of people didn’t pass?
Answer:
30.769230769231% or 4/13
Step-by-step explanation:
The fraction of people didn’t pass is 4/ 13.
We have,
Total number of people taking the test: 13
Number of people who passed: 9
So, the number of people who didn't pass
Number of people who didn't pass = Total number of people - Number of people who passed
Number of people who didn't pass = 13 - 9
Number of people who didn't pass = 4
So, the fraction of people didn’t pass
= 4/ 13.

It costs $520.00 to buy 4 ounces of gold. How much would it cost to buy six tenths of an ounce of gold?
6oz=$780.00
If it costs $520.00 for 4oz you first divide both numbers by 4 which should leave you with 1oz=$130.00 if you then multiply both sides by 6 you end up with your answer 6oz=$780.00

Tomatoes and cucumbers were planted in the garden in the ratio 4:1 there if there 14 cucumber plants how many tomato plants are there
Answer:
56
Step-by-step explanation:
14 cucumbers multiplied by 4 is 56 tomatoes
The number of tomato plants is 56.
Important information:
Ratio of tomatoes and cucumbers is 4:1.Number of cucumbers is 14.Ratio:Let [tex]x[/tex] be the number of tomato plants. Then,
[tex]\dfrac{x}{14}=\dfrac{4}{1}[/tex]
On cross multiplication, we get
[tex]x\times 1=4\times 14[/tex]
[tex]x=56[/tex]
Therefore, the number of tomato plants is 56.

a. Number of students in a class of 35 who turn in a term paper before the due date.
b. Gender of the next baby born at a particular hospital.
c. Amount of fluid (in ounces) dispensed by a machine used to fill bottles with soda pop.
d. Thickness of the gelatin coating of a vitamin E capsule
e. Birth order classification (only child, firstborn, middle child, lastborn) of a math major
Answer:
a. Numerical (discrete).
b. Categorical.
c. Numerical (continuous).
d. Numerical (continuous).
e. Categorical.
Step-by-step explanation:
In Mathematics, a categorical data can be defined as a statistical data type that is used to group informations having the same attributes or characteristics. Some examples of a categorical data are age, gender, race, religion etc.
A numerical data can be defined as a data set that is expressed in numbers only or a data set consisting of numbers rather than words. A numerical data is also known as a quantitative data.
Basically, numerical data are classified into two (2) main categories and these are;
1. Discrete data: a discrete data is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
2. Continuous data: a continuous data is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
a. Number of students in a class of 35 who turn in a term paper before the due date: this is a numerical data and it is discrete in nature because the number of possible values are finite or countable.
b. Gender of the next baby born at a particular hospital: this is a categorical data because it contains a nominal variable (gender).
c. Amount of fluid (in ounces) dispensed by a machine used to fill bottles with soda pop: this is a numerical data and it is continuous in nature because the number of possible values are infinite or uncountable.
d. Thickness of the gelatin coating of a vitamin E capsule: this is a numerical data and it is continuous in nature because the number of possible values are infinite or uncountable.
e. Birth order classification (only child, firstborn, middle child, lastborn) of a math major: this is a categorical data because it is used to categorize an information (birth order).

Which radical expression is equivalent to c^1/2
Answer:
it would be √c
Step-by-step explanation:
when you have fractional exponets, the denominator becomes the radical that you want to find so in this case since its 2 it would be he nomal √ (remeber that when you have a √ with no numbers. it automatically indciates that there is a two) , the numerator of the fraction is the exponent of the number that is inside the radical so in reality it would be √c^1 but we don't write the exponent 1 so it would be √c

okay i think this big enough for yall
Answer:
b(side length) = 15 centimeters
Step-by-step explanation:
Given an assumed regular rectangular prism which has a height of 18, and volume of 4050 cubic centimeters.
We are also given the formula b = (v/18)^1/2 which is said to find the side length of the rectangular prism. Therefore, it is implied that b must be the side length. Since we know everything except the side length we can substitute the volume since we are already given the height in the formula derived from the problem.
b = (4050/18)^1/2
b = (225)^1/2
b = 15
___________
We should also know that the volume of a rectangular prism is defined as V = l × w × h, with l as the length, w as the width, and h as the height, given that b is the side length which is multiplied by the width and height to get 4050, the base must be a square. Since 4050 = 15 × w × 18
4050 = 270 × w
4050/270 = w
15 = w
w = 15.
A square base is when the length and width are equal. Therefore this value has to be true.
As 15 × 15 × 18 = 4050.

The solutions to the trigonometric equation [tex]cos(\frac{\pi}{4} - x) = \frac{\sqrt{2} }{2} \cdot sin(x)[/tex] are;
{π/2, 3·π/2}
What is a trigonometric equation?A trigonometric equation is an equation involving trigonometric functions with the input of the function, represented by a variable. specified equation is presented as follows;
[tex]cos(\frac{\pi}{4} - x) = \frac{\sqrt{2} }{2} \cdot sin(x)[/tex]
The subtraction formula for the trigonometric ratios of cosine can be presented as follows;
cos(A - B) = cos(A)·cos(B) + sin(A)·sin(B)
Therefore;
cos(π/4 - x) = cos(π/4)·cos(x) + sin(π/4)·sin(x)
sin(π/4) = √2/2
Therefore;
cos(π/4 - x) = cos(π/4)·cos(x) + (√2/2)·sin(x)
cos(π/4 - x) = (√2/2)·sin(x)
cos(π/4)·cos(x) + (√2/2)·sin(x) = (√2/2)·sin(x)
cos(π/4)·cos(x) = (√2/2)·sin(x) - (√2/2)·sin(x) = 0
cos(π/4)·cos(x) = 0
cos(x) = 0/cos(π/4) = 0
x = arccos(0) = π/2 + n·π
Where n is an integer, therefore the values of the angle between 0, and 2·π are;
x = π/2 + π × 0 = π/2 and x = π/2 + 1 × π = 3·π/2
x = π/2 and x = 3·π/2
