selected a random sample of 45 stroke victims and found that the average cost of their rehabilitation if
$25,266 with a standard deviation of $3,251. At can it be concluded that the average cost at a large
hospital is different?
What is the p value?

step-by-step explanation: g=6

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer:

c) the x-coordinate of the center of the circle increases by 3
