The management of a chain electronic store would like to develop a model for predicting the weekly sales (in thousands of dollars) for individual stores based on the number of customers who made purchases. A random sample of 12 stores yields the following results: Customers Sales (Thousands of Dollars) 900 11.2 920 11.0 710 8.2 740 9.2 780 9.4 898 10.1 510 6.7 529 7.0 460 6.1 875 9.5 650 7.5 600 7.2 a. What is the response variable? b. ODGO Compute the coefficient of correlation. Interpret the value. C. Compute the coefficient of determination. Interpret the value. d. Construct the equation of least square regression line.
