Unit 7: Homework Assignment 1

In a manufacturing production process, two machines are being compared. The data below show the diameters, measured in millimeters, of a sample of ball bearings produced by each machine.Machine A                                              Machine B

1.95                                                          2.22

2.45                                                          2.30

2.50                                                          2.34

2.75                                                          2.28

2.38                                                          2.29

2.26                                                          2.25

2.33                                                          2.30

2.20                                                          2.27

2.16                                                          2.38

2.20                                                          2.34

Use Excel Template 6 (available in Canvas) to determine whether the variance in diameters differs between the two machines. Use a .05 level of significance.

Unit 7: Homework Assignment 2

Using Excel Template 7 (available in Canvas), find the correlation between miles driven by a sales representative for MediCap Pharmaceutical and the sales made. Part A asks you to use the “long way” of calculating, and Part B asks you to use the Data Tool to solve for the correlation.

Unit 7: Homework Assignment 3

Using Excel Template 7, find the correlation between miles driven by a sales representative, sales made, and sales calls made by using the Data Tool.
