Problem 1 4 2 points A customer has purchased 10 items, and spent 28 dollars. How long do you expect it takes to check this customer out, using the current preliminary model? Please round the coefficient estimates to the second decimal. 2.54 Checkout Time (minutes) Y 0.959 0.876 0.923 2.96 2.66 2.88 5 1 point Suppose we are interested in forecasting the time it takes to check out a customer in a supermarket. The scanner data collect the number of purchased items, and total amount of the purchase. The correlation matrix is provided below: Amount (S) X Amount ($) X Number of items X We are preliminarily fitting the following model, using JMP.
