4. [50 pts] Central Limit Theorem: Finding the smallest sample size
Each group of students will be assigned a set of two probability distributions, and, for each of these
distributions, will determine the smallest sample size for which the conditions of the CLT are satisfied.
Instructions: For each distribution, you must:
a. Include the command set.seed(value) as the first line in each R script, where value should be
replaced by the group number.
b. Simulate 100 samples (m = 100).
c. Vary the sample size (n =?) until you find the smallest sample size for which the conditions of the
CLT are satisfied.
d. Confirm your choice of n by replicating your analysis at least ten times.
e. Justify your selection with the use of probability plots, hypothesis tests, and descriptive statistics.
Deliverables: For each distribution, you must provide:
a. A commented R script
b. A minimum of three sets of results:
i. Results for 10 replicates on a sample size smaller than the suggested n for which the
conditions of the CLT are not yet satisfied
ii. Results for 10 replicates on the suggested n for which the conditions of the CLT are satisfied
iii. Results for 10 replicates on a sample size larger than the suggested n for which the conditions
of the CLT are satisfied
c. A thorough interpretation of outputs (probability plots, hypothesis tests, and descriptive statistics)
Hint: For each set of results, it is strongly recommended that you combine the information for the
descriptive statistics and the hypothesis tests in a table, where each row represents the results for a
single replicate. You may use the following table format:
Replica n Mean
