In the hypothesis testing, two type hypotheses are made, one is called Alternate

hypothesis and second is null hypothesis. What would be researched, it is called Alter

hypothesis and in against of alternate hypothesis called Null hypothesis.

Ans. 1 The average (mean) sales per week exceed 41.5 per salesperson:

, Math 2

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).
