You are given the same test scores (x) and weekly sales (y) data as in problem 7a. Weekly Sales (y)-in thou, of dollars Salesperson Mr. Amber Test Score (x) 4 1. $6 $12 $4 $8 2. Mr. Archer 3 6 3. Ms. Smith 4. Mr. Malcolm 5. Ms. Goodwin $1 10 What is the regression equation that can be estimated from this data? (i.e., of the form y'=a+bx where y' stands for predicted.) What is the standard error of the estimate? Construct 90% confidence intervals for the mean value of y given that x=4.
