Your typed answer is the driver of your grade: show your solution and justify using written English. You must show work to get full credit on each question. As well as for partial credit when your final answer is wrong.    In addition to typing, you can email your handwriting work within 30 minutes of finishing this exam.  Instructions to email supporting handwriting notes: after completing and submitting the exam on Canvas, scan your notes and email them to ppimentelfur@umass.edu with the title “MIE 654 Final Exam Notes for STUDENT_NAME”. Use a scanner or scanning app for better quality; if the instructor cannot understand your notes, they will not be considered. You can only use your phone after submitting the exam; otherwise, Honorlock will flag you for dishonesty.   Please indicate your choice below:

Compute in your Excel file the Confidence Interval (both the Lower & Upper Limits). [2 points] (You will earn these points only if the computations using Excel formulas appear in your file for the confidence interval)   Type-in here the Confidence Interval (rounded to four digits after the decimal). [1 point] Conduct the Hypothesis Test using the Confidence Interval approach (Type in the entire logic in a sentence). What is the decision on the Hypothesis Test? [1 point]

Problem 3 Description: A study was performed to determine whether men and women differ in their repeatability in assembling components on printed circuit boards. Random samples of 25 men 21 women were selected, and each subject assembled the units. The two sample standard deviations of assembly time were 0.98 minutes for men 1.02 minutes for women. Is there evidence to support the claim that men and women differ in repeatability for this assembly task at 0.08 level of significance?   Use Excel to do all the computations. Answer all the questions below and upload your Excel file to the last question and submit.
