Question

Noah is studying dogs to determine their interest in blue toys versus red toys. He splits a group of 20 dogs into 2 groups. One group is given blue toys and the other is given red toys. Noah has the dogs play with the toys until they lose interest. He finds that the dogs that had blue toys played with them 2 minutes longer than the dogs that played with red toys. Noah rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Noah conclude the difference is significant?

Answer 1

A. Yes, Anthony can conclude the difference is significant because a 2-minute difference is not likely to happen by chance.
B. No, Anthony cannot conclude the difference is significant because a 2-minute difference is likely to happen by chance.
C. Yes, Anthony can conclude the difference is significant because 0.25 is the difference in means that occurs most often.
D. No, Anthony cannot conclude the difference is significant because 0.25 is the difference in means that occurs most often.
