Answer:
Kindly check explanation
Step-by-step explanation:
The alpha level set at the beginning of of an experiment is used by the researcher to the limit the probability if making a type 1 error. The type 1 error is committed when a true null hypothesis is incorrectly rejected.
The type 2 error on the other hand is committed when fail to reject a false null hypothesis.
Hence, in other to forestall the risk of incorrectly rejecting a true null hypothesis, the alpha level is set.
When critical region is split across both tails of the distribution, The z-score boundaries at an alpha level α = .05
α = .05 (95% confidence level)
When region is split into 2:
α/2 = .05/2
α/2 = 0.025
Loooking up the z table for the Zscore with probability of 0.025
Zscore = ±1.96
The alpha level, which would be chosen at the start of an investigation, is utilized by the investigator to restrict the likelihood of making a type 1 error and the z-score will be "[tex]\pm[/tex] 1.96".
Type 1 error and ProbabilityAccording to the question,
Whenever the genuine null hypothesis has been wrongly dismissed or discarded, a type 1 problem happens.
When the crucial zone is divided between the distribution's two tails. At an alpha level, the z-score boundaries be:
95% confidence level, α = 0.05
Now,
→ [tex]\frac{\alpha}{2} = \frac{0.05}{2}[/tex]
By applying cross-multiplication, we get
[tex]\frac{\alpha}{2} = 0.025[/tex]
hence,
By using the z table,
Z-score = [tex]\pm[/tex] 1.96
Thus the above answer is correct.

Find the midpoint between the pair of points using the Midpoint
Formula. *
(7,-2) and (-4, 2)
Given parameters:
Coordinates = (7,-2) and (-4, 2)
The formula for the coordinate of the mid point is;
[tex]x_{m}, y_{m}[/tex] = ( [tex]\frac{x_{1} + x_{2} }{2} , \frac{y_{1} + y_{2} }{2}[/tex] )
where;
[tex]x_{m}, y_{m}[/tex] are the coordinates of the mid points
x₁ = 7 y₁ = -2
x₂ = -4 y₂ = 2
Input the parameters and solve;
[tex]x_{m}, y_{m} = \frac{7 + (-4)}{2} , \frac{-2 + 2}{2}[/tex]
[tex]x_{m}, y_{m}[/tex] = [tex]\frac{3}{2} , 0[/tex]
So the mid point is at [tex]\frac{3}{2} , 0[/tex]

Step-by-step explanation:
Matched pairs t test is used for paired data. Data sets are "paired" when the two sets have the same number of data points and each data point in a set is related to only one data point in the other set.
A good example is before/after data. Each set has the same number of data points, and each data point in the after set is related to one in the before set.
B is not an option because, although the samples are the same size, there is not a paired relationship between the sets.
C is not an option because the samples are not the same size.

solve for m p=mnq, whats the answer
Easy buddy...
[tex]p = m \times n \times q[/tex]
Divided the sides of the equation by n
[tex] \frac{p}{n} = m \times q \\ [/tex]
Divided the sides of the equation by q
[tex] \frac{p}{n \times q} = m \\ [/tex]
So
[tex]m = \frac{p}{nq} \\ [/tex]

if k-9=5(k-3)find k
Answer:
K = 3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
k−9=5(k−3)
k+−9=(5)(k)+(5)(−3)(Distribute)
k+−9=5k+−15
k−9=5k−15
Step 2: Subtract 5k from both sides.
k−9−5k=5k−15−5k
−4k−9=−15
Step 3: Add 9 to both sides.
−4k−9+9=−15+9
−4k=−6
Step 4: Divide both sides by -4.
-4k/-4 = -6/-4
K = 3/2
7. The graph of part of linear function g is shown on the grid. Which inequality best represents the domain of the part shown?
Answer:
a
Step-by-step explanation:
Domain means the change in x.
so the domain will be which values of x the fn goes through.
you can see the black line goes from -9 to 2 in x values.
the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without.
so x is between -9 and 2, 2 is with equals -9 is without,
so the first one.
The inequality best represents the domain of the part shown should be -9<x ≤2.
What is domain?Here domain means the change in the x. Here the domain should be the values of with respect to fn. Also, here we have to watch the blank line that goes from -9 to 2 in x values.
Since 9 should not be filled however 2 should be.
hence, The inequality best represents the domain of the part shown should be -9<x ≤2.

B)
[tex] \frac{c - a}{b} \times \frac{ - d}{e} = - 1[/tex]
C)
[tex] \frac{c - a}{b} = \frac{ - d}{e} [/tex]
D)
[tex] \frac{c - a}{b} = \frac{d}{e} [/tex]
Answer:
b/a=c/d Two lines are parallel to each other if they have the same slope. So let's look at the options and see which one matches that statement. b/aâ‹…c/d=â’1 * This is checking to see if the two lines are perpendicular to each other. Almost the exact opposite of parallel. So this is the wrong answer. b/a=c/d * b/a is a legitimate slope. c/d is also a good slope. And they're being checked to see if they're equal to each other. So this is the correct answer. But let's see if the next two options will give us a chuckle or two. b/a=d/c * b/a is OK. d/c almost looks ok, check the figure. And d/c is NOT a slope. The slope is delta Y over delta X. And d/c is delta X over delta Y. The inverse of the slope. So comparing those two values is meaningless. So it's a wrong answer. b/aâ‹…d/c=â’1 * And they're trying the inverse of the slope trick again. WRONG. And they're checking if it's perpendicular. Also wrong. So definitely not a good choice.
