From Professor Mikula:
a. Define your sampling plan and why you chose this plan. Discuss any potential sampling bias. (10 pts)
i. Census, Random Sampling, Stratified, Cluster, Systematic, and Convenience.
b. Plot your data for HM and J together on an individuals value plot with a horizontal line at the mean of your sample (5 pts).
c. Plot your data on the same individual value plots grouped by sections HM and J with the horizontal lines at the mean age for HM and the mean age for J. (5 pts)
d. Construct a 95% confidence interval for the mean age of books at the Mardigian Library for each section HM and T together (5 pts).
e. Construct a 95% confidence interval for the mean age of books at the Mardigian Library for each section HM and T separately (10 pts).
f. Do you think these interval estimates are a good estimate? Why or why not? (5 pts)
2. Identify what is wrong with the following sentences and explain why. Rewrite the sentence correctly: Each part is worth 5 pts.
a. Reject the null hypothesis, there is enough evidence to prove the alternative hypothesis.
b. Fail to reject the null hypothesis, there is is not enough evidence to support the alternative hypothesis, therefore the null hypothesis is true.
