If the number of people working is 2 standard deviations above the mean, how many standard deviations above do you expect sales to be?

what value of sales would that correspond to?

if the number of people working is 1 standard deviation below the mean, how many standard deviations above or below the mean do you expect sales to be?

what value of sales does that correspond to?

find the slope estimate of b1.

what does b1 mean, in this context?

find the intercept b0.

what does b0 mean, in this context?
