# Question

The following table shows the number of inquiries for a sample of job opening announcements that your company has posted on two different websites, JobSite.com and Jobs!. com.

a. Using a significance level of .05, construct the appropriate hypothesis test to test a null hypothesis that there’s no difference in the average number of job inquiries that your company receives from the two websites. Assume that that the two population distributions represented here have unequal standard deviations.

b. Compare your result in part a to the result you would produce if you assume that the two population distributions have equal standard deviations.
