PLEASE HELP !! When finding the margin of error for the mean of a normally distributed population from a sample, what is the critical probability, assuming a confidence level of 58%? 0.21
0.42
0.58
0.79

D) 0.79

Step-by-step explanation:

First, find alpha.

= 1 - (confidence level / 100)

= 1 -

= 1 - 0.58

= 0.42

Then, you can solve for the critical probability.

p* = 1 -

p* = 1 -

p* = 1 - 0.21

p* = 0.79

1. 8

2. 9

3. 20

4. 3

5. 17

6. 2.2

7. 11.25

8. 1

9. 14

10. 2

step-by-step explanation:

thats the first half

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
