Please make correction on Part 3 and Part 4. In Part 4 of our project, we investigate two claims about our data set: Claim 1: The average age of online students is 32 years old. Claim 2: the proportion of males in online classes is 35%. Grading for Claim 1 Your Null hypothesis is correct but your alternate hypothesis is not. Null and alternate hypotheses (-2 pts) Both your sample mean and sample standard deviation are incorrect and should have been corrected from the previous part of the project before attempting this part. You should redo this part of the project and resubmit. Sample mean and standard deviation (Carried over from previous parts of the project) Distribution is T-Distribution (-3 pts) Test Statistic with Calculation (-3 pts) p-value (-3 pts) Decision (2 pts) Interpretation (3 pts) There is not enough evidence to conclude that the mean age of online college students differs from 32 years old. Grading for Claim 2 For this claim, your test statistic, p-value, decision and interpretation are all incorrect. Null and alternate hypotheses (4 pts) Sample Proportion of Males and Females (Carried over from previous parts of the project) Distribution is Normal (2 pts) Test Statistic with calculation (-3 pts) p-value (-3 pts) Decision (-2 pts) Interpretation (-3 pts) There is not enough evidence to conclude that the proportions of males in online classes differs from 35%.
