Data set 1 assignment presents a sample of the number of defective flash drives produced by a small manufacturing company over the last 30 weeks. The company’s operations manager believes that the number of defects produced by the process is less than seven defective flash drives per week. Use this online calculator (or any statistical package that you are comfortable with) to construct a hypothesis test to verify the operations manager’s claim. Your hypothesis test should include null and alternative hypotheses, a t test statistic value, a p value, a decision, and a conclusion. Submit a Word file that includes the hypothesis Case analyses assignment The vice-president of administration at your company wonders whether employees are taking adequate amounts of vacation time. Employee burnout is a concern. Research suggests that an employee taking less than 1.4 weeks of vacation annually is very likely to experience burnout. You are asked to analyze the employee vacation data and conduct a hypothesis test with the following results: t = 2.93 p = 0.0084 What factors should the vice-president consider in determining the presence of employee burnout? Do employees take more than 1.4 weeks of vacation? What reasons should the vice-president provide to the president to justify the recommendation on employee burnout?

Use Excel’s ToolPak (or any statistical package that you are comfortable with) to compute descriptive statistics for the data. Submit your statistical output from Excel , which should include values for the mean, median, mode, samp le variance, and sample standard deviation. Module Four , Correlation and Regression : Data set 2 presents a sample of the number of defective flash drives produced by a small manufacturing company over the last 30 weeks. Use Excel’s Analysis ToolPak (or a ny statistical package that you are comfortable with) to compute the regression equation for predicting the number of defective flash drives over time (in weeks), the correlation coefficient r, and the coefficient of determination R 2. Submit your statistic al output from Excel , which should include values for the slope, y-intercept, regression equation, r, and R2. Module Six, Hypothesis Testing : Data set 2 presents a sample of the number of defective flash drives produced by a small manufacturing company o ver the last 30 weeks. The company’s operations manager believes that the number of defects produced by the process is less than seven defectiv e flash drives per week. Use this online calculator (or any statistical package that you are comfortable with) to construct a hypothesis test to verify the operations manager’s claim. Your hypothesis test should include null and alternative hypotheses, a t test statistic value, a p -value, a decision , and a co nclusion. Submit a Word file that includes the hypothesis test. Specifically , the following critical elements must be addressed: I. Methodology II. Analysis Guidelines for Submission: Submit a 1-page Word document with att ached spreadsheet if required. The ass ignments in Modules Two and Four each require a spreadsheet. Instructor Feedback : This activity uses an integrated rubric in Blackboard.
