If the population mean is $420, what is the probability the null hypothesis will be rejected (using the rejection region you calculated above)? give your answer in the following format: 0.0450 (if it is 0.045) or 0.2345 (if it is for example 0. i. e. use 4 decimals for your answer.

send it over

step-by-step explanation:

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.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
