Phase 3 - Task 1
Task Type: Discussion Board
Deliverable Length: 400-450 words
Primary Discussion Response is due by Wednesday
You're trying to explain null and alternative hypotheses to one of the senior managers at Company W and he's not "getting it" when you use snack food sales. Help him by thinking about a business problem in another organization or department. Formulate a null hypothesis and the corresponding alternative hypothesis that could be tested.
Also, please state the business implications of Type I and Type II errors for those examples.
Phase 3 - Task 2
Task Type: Individual Project
Deliverable Length: 700-1000 words
Company W is testing a sales software package. Their sales force of 500 people is divided into four regions: Northeast, Southeast, Central and West. Each sales person is expected to sell the same amount of products. During the last 3 months, only half of the sales representatives in each region were given the software program to help them manage their contacts.
The VP of Sales at WidgeCorp, who is comfortable with statistics, wants to know the possible null and alternative hypotheses for a non-parametric test on this data using the chi-square distribution. A non-parametric test is used on data that is qualitative or categorical, such as gender, age group, region, and color. It is used when it doesn’t make sense to look at the mean of such variables. (You can refer to the article for this week for further information located at the end of the Phase Resources.)
