Running Head: Course Project Part-B Math-533 Hypothesis Testing By: Sagar Patel Professor: Terrance Encalarde Keller Graduate School of Management June 10th, 2017 Running Head: Course Project Part-B A hypothesis testing involves the testing of the null hypothesis and the alternative hypothesis. When testing the hypothesis, either the null hypothesis or the alternative hypotheses is rejected. The Company can use hypothesis testing to examine if it should keep a current process, change a current process or start a new process. It can also examine different areas to see if an employee or manager’s ideas would prove more productive. The hypothesis testing can quickly be applied or tested saving the Company time and money. Requirement A: The Average Mean Sales per Week exceeds 41.5 per salesperson. Key Statistics were computed using Minitab Descriptive Statistics: Sales (Y) Variable SALES NUMBER 100 MEAN 42.55 SE MEAN 0.717 ST.DEVIATION 7. 5 VARIANCE 51. 2 MINIMUM 21 Q1 39 MEDIAN 43 Q3 47 MAXIMUM 67 RANGE 46 One-Sample Z: Sales (Y) The assumed standard deviation = 7.171 Variable N Mean St-Dev SE Mean 95% CI Sales (Y) 100 42.550 7.171 0.717 (41.145, 43.955) One-Sample Z: Sales (Y) Test of mu = 41.5 vs 41.5
