This week you will begin working on Phase 4 of your course project. For Phase 4 of your course project, you will want to review your instructor’s feedback from your Phase 1, Phase 2, and Phase 3 submissions to make any necessary corrections. Remember if you have questions about the feedback to ask your instructor for assistance.<\/p>\n

\u00a0<\/p>\n

Corrections:<\/p>\n

Phase 1: incorrect:\u00a0 median (incorrectly rounded), variance (divide by 59 instead of 60), standard deviation.<\/p>\n

Phase 2: Confidence intervals were incorrect, but only slightly – your s.d. was incorrect and should have been 8.92 – use this going forward.<\/p>\n

The CI = x-bar +\/- t * s \/ sqrt (n),<\/p>\n

Phase 3:<\/p>\n

Use p for proportions or percents, this was a test of means, so use “mu” in hypotheses statements; \u03bc = 65 for example;<\/p>\n

Your critical value was incorrect; use t-table instead of z;<\/p>\n

This whole exercise was just like example #4 in the Mod 3 course materials \u2013 Hypothesis Testing Explained and Explored;\u00a0<\/p>\n

\u00a0<\/p>\n

Once you have made your corrections, you will compile your information from Phase 1, Phase 2, Phase 3 and your final conclusion into one submission and submit this as your rough draft for Phase 4 of the course project.
