MATH 534 Week 6 Course Project Part B: Hypothesis Testing and Confidence Intervals LATEST 2021 PROJECT WITH ASSURED GRADE A+ Using the same data given for Part A, this report will show the hypothes... is testing and confidence intervals. Hypothesis testing is a statistical method that is used in making statistical decisions using experimental data. The testing involves testing the alternative and null hypothesis which one will be rejected. Descriptive Statistics Sales (Y) Mean 42.62 Standard Error 0.503679391 Median 42.5 Mode 41 Standard Deviation 5.036793914 Sample Variance 25.36929293 Kurtosis -0.522943834 Skewness -0.006883357 Range 23 Minimum 30 Maximum 53 Sum 4262 Count 100 A. The first hypothesis test performed will be when the mean sales per week exceeds 41.5 per salesperson. Since the average sales per person exceeds There is sufficient evidence to reject the null based off the number listed below. The null and alternative hypothesis are Ho: = 41.5 and H1: = 41.5. Level of Significance = .05. n = 100 Sample Mean: 42.55 B. Testing to see if proportion receiving online training is less than 55%. Level of Significance = .05. [Show More]
