In this module you will submit Phase 5, the final phase, of your course project. For Phase 5 of your course project, you will want to review your instructor’s feedback from your Phase 4 submission and make any necessary corrections
Once you have made your corrections, you will make your final submission for the course project. Below is a summary of the expectations for Phase 5 of the course project:
Discuss the process for hypothesis testing.
I did not do the rough draft for phase four.
In this module, 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.
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
Teachers feed back from the first 3 stages
You did an excellent job on your course project phase 1! You earned full credit by meeting all requirements. Your work demonstrated advanced understanding of descriptive statistics.
Course Project – Phase 1 Scoring Rubric:
Includes a clear and concise introduction for the selected topic and data set. Introduction includes all required elements as outlined in the assignment. (5/5)
Clearly discusses the importance of the measures of center and measures of variation. (5/5)
Correctly calculates and interprets the measures of center and measures of variation. (10/10)
Includes a clear and concise conclusion that summarizes the paper.(5/5)
Accurately uses APA formatting consistently throughout the paper. The equation editor was used to format all equations. (5/5)
Thank you for constructing confidence intervals for the scenario 1. You discuss the importance of the confidence intervals(7/7), and accurately use APA formatting consistently throughout the paper and submit assignment on time. The equation editor was used to format all equations(6/6). But some calculates and interprets the 95% and 99% confidence intervals are not correct.
Please take a look at the following results(15/17):
Sample standard deviation s=19360
sample size n=350
degrees of freedom=n-1=349
95% confidence interval with 349 degrees of freedom
Margin error E=t*s/sqrt(n)=2035.296
confidence interval:60303.7 < mean <64373.3
Thank you for performing the hypothesis test for the scenario 1. You clearly discuss the steps for hypothesis testing(10/10), and accurately use APA formatting consistently throughout the paper. The equation editor was used to format all equations(6/6).But some results in your hypothesis test are not correct. Please take a look at the following(10/14):
Sample standard deviation s=19,360
sample size n=350
degrees of freedom=n-1=349
H0 : μ = 65,000
H1 : μ < 65,000
Conduct the hypothesis test for the population mean μ, we use the t-statistic
which follows a t-distribution with n-1=349 degrees of freedom.
The critical value is -1.649
Phase 4 was a rough draft for phase 5. Any questions please call me.
