A researcher working for the Ray-Ban Corporation decides to perform a hypothesis test to investigate whether there is a significant positive correlation between monthly temperature and number of sunglasses sold at one of their locations. The researcher randomly selected the following sample from this location. Monthly Temperature (F) Number of Sunglasses Sold 75 76 61 52 56 79 99 89 71 74 95 120 43 71

(TEMP SUMS: begin inline style sum for blank of end styleX = 500; begin inline style sum for blank of end styleX2 = 38,198) (NBR SUMS: begin inline style sum for blank of end styleX = 561; begin inline style sum for blank of end style X2 = 47,559)

The decision rule for this hypothesis test at = 5% is:

a. Reject Ho if the test statistic is greater than the critical r value r = 0.58.

b. Reject Ho if the test statistic is greater than the critical r value r = 0.67.

c. Reject Ho if the test statistic is either less than the critical r value r = - 0.75 or greater than the critical r value r = 0.75

d. Reject Ho if the test statistic is less than the critical r value r = - 0.67.

e. Reject Ho if the test statistic is less than the critical r value r = - 0.58.
