Question

select the correct answer. a local grocery store decides to offer a free piece of fresh fruit (banana or apple) to all shoppers in the produce department. the store is conducting an observational study to determine which type of fruit is selected more often. at the end of the first day, the store found that twice as many shoppers select an apple. the grocery store then repeats the observational study for 14 days. all studies yield similar results. what generalization can be made from the results of this study? a. given the choice of a banana or an apple, twice as many shoppers will select an apple. b. there is not enough information to generalize the studys results. c. the results are inconclusive; therefore, a generalization cannot be made regarding which type of fruit is preferred by most shoppers. d. given the choice of any type of fruit, twice as many shoppers will select an apple.

Explanation:

To make a generalization from an observational study, consistent results over multiple trials are needed. Since the study was repeated for 14 days and all studies yielded similar results (twice as many shoppers selected an apple on the first - day and this pattern likely continued), we can generalize that given the choice of a banana or an apple, twice as many shoppers will select an apple.

Answer:

A. Given the choice of a banana or an apple, twice as many shoppers will select an apple.
