Using hypothesis testing, the critical value of z for a 5 percent level of significance, left-tailed test is -1.645.
(a) For a 10 percent level of significance, two-tailed test, the critical value of z is:
z_critical = ± invNorm(1 - (0.10/2))
where invNorm is the inverse normal cumulative distribution function. Evaluating this expression gives:
z_critical = ± 1.645
Therefore, the critical value of z for a 10 percent level of significance, two-tailed test is ±1.645.
(b) For a 1 percent level of significance, right-tailed test, the critical value of z is:
z_critical = invNorm(1 - 0.01)
Evaluating this expression gives:
z_critical = 2.326
Therefore, the critical value of z for a 1 percent level of significance, the right-tailed test is 2.326.
(c) For a 5 percent level of significance, left-tailedtest, the critical value of z is:
z_critical = invNorm(0.05)
Evaluating this expression gives:
z_critical = -1.645
Therefore, the critical value of z for a 5 percent level of significance, left-tailed test is -1.645.

Step-by-step explanation:
The midpoint of AB is (-5,1), if A(-3,8) and B(-7,-6). How to find out the midpoint of coordinates?The midpoint of coordinates is found by measuring the distance between two endpoints and dividing the obtained result by 2. Apart from this, one more method is there which is to add the two X-coordinates of the endpoints and divide them by 2. The same concept is applied to the Y-coordinates as well. According to the question, A = (-3,8) and B = (-7,-6). The formula is as follows:M(x,y) = ((x₁+x₂)/2 , (y₁+y₂)/2). Putting the above values in the mentioned formula, we get:M(x,y) = ((-3-7)/2 , (8-6)/2).
M(x,y) = (-5 , 1). Therefore, the midpoint of AB is (-5,1), if A(-3,8) and B(-7,-6).To learn more about the Midpoint of coordinates, refer to the link: brainly.com/question/28308761
Answer:
b. -5/2
Step-by-step explanation:
You chose the correct answer,
The slope of a perpendicular line is the opposite reciprocal of the original slope. This means flip the fraction and add a negative sign. 2/5 --> -5/2.
