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).

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
