Question

Anthony is studying how quickly children tire based on the amount of sugar they ingest. He splits a group of 20 children into 2 groups. One group is given sugar and the other is not. Anthony asks the children to start playing at a playground at the same time, and to stop when they tire, measuring the time each child stops playing. He finds that the children who did not ingest sugar played 2 minutes longer than those who did ingest sugar. Anthony rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below.

Answer 1

based on the data can anthony conclude the difference is significant?

Answer 3

So my options are:
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.

Answer 10

I can't see the plot very easily, can you take another picture, one that has the title perhaps?

Answer 11

there isnt a title for it but the answers having to do with the plot are wrong anyway

Answer 12

d is wrong

Answer 13

Oh, Okay.. Well, I don't think it's enough to calculate a conclusion unless the average of all of them was 2 minutes. So, I'd say B

Answer 14

ok thank you so much!
