Refer to question 70. Use the MINITAB program in terms of the regression approach to forecast accounts receivable in 1991. Compare your results to those you got with the ratio method in question 70.

Question 70

A company is interested in estimating the value of accounts receivable for its 75 stores. To do this, the company collects information on 1990 and 1991 accounts receivable from a simple random sample of 10 stores. The results of this sampling study are given in the table.

Suppose 1990 accounts receivable were $ 1.4 million. Use the ratio method to estimate the accounts receivable for 1991.
