In the given problem, it will test that the sales per week is more than 41.5 per
sales person. It is important question which test will be applied. In this scenario, single
tail test will be done because only one side of result will be checked. On the other hand,
sample size is greater than 30. So Z score will be calculated to test the alternate
hypothesis. Units are taken in $1000 (Anderson, Sweeney & Williams, 2011).
