proportion.

Short answer

on the graph with the areas, upper and lower limits of the confidence interval, and the sample

proportion.

Step-by-step solution

Given Information

on the graph with the areas, upper and lower limits of the confidence interval, and the sample

proportion.

Calculation

The 92% confidence level is CL = 0.92

The area under each tail is a/2 = 0.04

The 92 percent confidence interval is calculated as follows: (0.7217,0.8783)

The sample fraction of girls aged 8 to 12 at the start of ice skating instruction at the ice chalet at 0.8

p' = 0.8

Explanation

The values are then entered into the supplied figure blank.
