Mathematics Homework Help

this is what the grader stated:

• Did not correctly solve a majority of the problems or at least one problem left blank. [1]
• Good effort overall. There were a few areas needing some improvement:
• Q2: The p-value and CV were incorrect, but good try.
• Q3: Good attempt, but the comparison of the t Stat to the p-value is the wrong method of comparison to make a decision whether to reject the null or not.
• Q4: The hypothesis setup was a good try, but not correct. Review the correct way to set up a Hypothesis test using the correct notation and correct inequality symbol for the alternative hypothesis corresponding to the scenario.
• Q5: The CV, tStat, and p-values were all a good try, but unfortunately, not the correct values.
• Q6: This was a good try, but needs to be redone using either the CV method or the p-value method to make a decision. Great effort though!
