A regional retailer would like to determine if the variation in average monthly store sales can, in part, be explained by the size of the store measured in square feet. A random sample of 21 stores was selected and the store size and average monthly sales were computed. The results are shown in the accompanying table. Complete parts a through c below. Use a 0.025 significance level where needed. Click the icon to view store size and average monthly sales data. Click here to view the scatter plot a. Click here to view the scatter plot d. Click here to view the scatter plot c. Based on the scatter plot, a positive linear relationship appears to exist between the two variables. b. Calculate the sample correlation coefficient between store size and average monthly sales. The correlation coefficient is 0.846 (Round to three decimal places as needed.) c. Conduct a hypothesis test to determine if a positive correlation exists between store size and average monthly sales. Use a level of significance of 0.025 Identify the null and alternative hypotheses. Ho: P HA P (Type integers or decimals. Do not round.)
