(02.04 HC) A random sample of online makeup tutorial videos and sales of makeup was measured, and the computer output for regression was obtained:

Coefficients Standard Error t Stat P-value
Intercept −7.567857143 0.426240686 −17.7549 1.04E-05
Makeup Tutorial Videos 0.917857143 0.028166777 32.58652 5.11E-07

R-sq. = 99.53% R-sq. (adj) = 99.44%

Part A: Use the computer output to determine the LSRL. Identify all the variables used in the equation. (3 points)
Part B: What proportion of the variation in makeup sales is explained by its linear relationship to makeup tutorial videos? Explain. (4 points)
Part C: Determine if increased makeup sales were caused by online makeup tutorial videos. Explain your reasoning. (3 points)

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.
