Astudy done by researchers at a university concluded that 70% of all student athletes in this country have been subjected to some form of hazing. the study is based on responses from 1200 athletes. what are the margin of error and 95% confidence interval for the study?

The margin of error is 0.01323 and 95% confidence interval is (0.674,0.73).

Step-by-step explanation:

Since we have given that

p = 0.70

n = 1200

We need to find the margin of error;

Margin of error would be

At 95% confidence level, α = 1.96

so, 95% confidence interval would be

Hence, the margin of error is 0.01323 and 95% confidence interval is (0.674,0.73).

step-by-step explanation:

i think you should think about the question and not look online.

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!
