For both parts, pick the hardest concept to learn for statistics, then explain why.

Part 1:

a. Apply and interpret the central limit theorem for sums.

b. Calculate and interpret confidence intervals for estimating a population mean and a population proportion.

c. Interpret the Student's t probability distribution as the sample size changes.

d. Discriminate between problems applying the normal and the Student'stdistributions.

e. Calculate the sample size required to estimate a population mean and a population proportion given a desired confidence level and margin of error.

Part 2:

a. Understand the basis of hypothesis testing

b. Perform hypothesis tests for a single population proportion

c. Perform hypothesis tests for a single population mean

d. Perform hypothesis tests for two population proportions using independent samples

e. Perform hypothesis testing for two population means using independent samples

f. Perform hypothesis testing for two population means using dependent samples.
