Answer:
1.
Step-by-step explanation:
I am 100% positive.
If you look at the bottom of the graph you see number from 0-14 counting by 2's. Those numbers stand for how many girls/boys there are exactly.
The colored lines represent boys/girls and you can determine which is which by looking at the two boxes on the right and reading the labels. Looking at the cookies and cream two lines you see that the girl one is longer. If you look back at the bottom and see which number both lines are lined up to you can determine which is on a higher number. That would be your answer.
Hope this helped lots and lots,

Answer:
Step-by-step explanation:
For this case we have the following data:
represent the random sample 1 selected
represent the proportion of success for the sample 1 selected
represent the random sample 2 selected
represent the proportion of success for the sample 2 selected
We know for this case that we can use the normal approximation since for both cases we have:
We have the randomization condition and we assume that the two samples are <10% of the entire population size.
So then we can use the following distribution for the proportions:
For this case we want to find the distribution for the difference of these two proportions and we have this:
So then the dtandard deviation would be given by:
Answer:
as if it was on the y axis it would be equal
Answer:
m = slope
(x_1, y_1) = coordinates of first point in the line
(x_2, y_2) = coordinates of second point in the line
