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 re-randomizes 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? (3 points)
dot plot ranging from negative two to two in increments of point five with frequencies of two, three, four, five, six, nine, six, twelve, fifteen, twelve, nine, ten, five, four, three, and two respectively
No, Noah cannot conclude the difference is significant because a 2-minute difference is likely to happen by chance.
Yes, Noah can conclude the difference is significant because a 2-minute difference is not likely to happen by chance.
Yes, Noah can conclude the difference is significant because 0.25 is the difference in means that occurs most often.
No, Noah cannot conclude the difference is significant because 0.25 is the difference in means that occurs most often.
