1. there are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. the first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. the line plot shows the differences after 10 rerandomizations. determine whether the difference in the means of the two groups is significant based on the line plot. explain your answer.

i assume the line plot is the % difference, the original 95% vs 92% has a difference of 3%,

the 10 random values center around 3% and 3% has the most occurrences of the 10.

the average value for the 10 is 2.9%, so that is within .1 of the original 3%

so it should be significant, not sure what criteria you are supposed to use?

is there a p or z test involved?

Hope this helps!

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
