Use a sample n=5 A sample of size n = 200 has a known population standard deviation of 15.0. The population appears to be skewed. Determine whether a margin of error should be calculated using a

critical value of a 2. a critical value of ta 2. or neither

a critical value ofta2

a critical value of 2/2

neither00 p=0.90 and a 95%

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
