Answer to Question 1

We are 95 confident that the true long run proportion of new product placements is in the interval (0.414, 0.502). By 95 confident we mean that if this experiment is conducted several times and a confidence interval is calculated for each trial, we expect 95 of them to include the true long run proportion.

Answer to Question 2

C
