The regional sales manager for American Toys, Inc., recently collected data on weekly sales (in dollars) for the 15 stores in his region. He also collected data on the number of salesclerk work hours during the week for each of the stores. The data are as follows:

a. Develop a scatter plot of these data. Determine which variable should be the dependent variable and which should be the independent variable.
b. Based on the scatter plot, what, if any, conclusions might the sales manager reach with respect to the relationship between sales and number of clerk hours worked? Do any stores stand out as being different? Discuss.
