3. There are 30 students who started a computer programming class in 7th grade and 30 students who started in 9th grade. The first group had a mean final project grade of 95% and the second group has a mean 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.

the square root of what number? if you add that, then someone will probably answer the question.

x + 4/7

step-by-step explanation:

use cymath

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
