Sara is studying how quickly adults tire after eating turkey. She splits a group of 20 adults into 2 groups. One group is given
turkey to eat and the other group is not given anything to eat. Sara asks the adults to start exercising at the same, and to stop when they tire, measuring the time each adult stops exercising. She finds that the adults who did not eat turkey exercised 2 minutes longer than those who did eat turkey. Sara rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Sara conclude the difference is significant?
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, Sara cannot conclude the difference is significant because a 2-minute difference is likely to happen by chance.
Yes, Sara can conclude the difference is significant because 0.25 is the difference in means that occurs most often.
No, Sara cannot conclude the difference is significant because 0.25 is the difference in means that occurs most often.
Yes, Sara can conclude the difference is significant because a 2-minute difference is not likely to happen by chance.
