Answer:
At 95% confidence level, the difference between the proportion of freshmen using steroids in Illinois and the proportion of seniors using steroids in Illinois is -7.01135×10⁻³ <
< 1.237
Step-by-step explanation:
Here we are required to construct the 95% confidence interval of the difference between two proportions
The formula for the confidence interval of the difference between two proportions is as follows;

Where:

n₁ = 1679
n₂ = 1366
at 95% confidence level = 1.96
Plugging in the values, we have;

Which gives;
-7.01135×10⁻³ <
< 1.237.
At 95% confidence level, the difference between the proportion of freshmen using steroids in Illinois and the proportion of seniors using steroids in Illinois = -7.01135×10⁻³ <
< 1.237.
