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 issigni

Best ResponseYou've already chosen the best response.0A No, Sara cannot conclude the difference is significant because a 2minute difference is likely to happen by chance. B Yes, Sara can conclude the difference is significant because 0.25 is the difference in means that occurs most often. C No, Sara cannot conclude the difference is significant because 0.25 is the difference in means that occurs most often. D Yes, Sara can conclude the difference is significant because a 2minute difference is not likely to happen by chance.

Best ResponseYou've already chosen the best response.1your plot is not labeled, but I assume the xaxis is the difference in time measured in minutes. 2 minutes is not likely, so I would say the difference is significant.
