Chapter 8, Problem 50P
A study was conducted of genetic and environmental influences on cholesterol levels. The data set used for the study were obtained from a twin registry in Sweden [10]. Specifically, four populations of adult twins were studied: (1) monozygotic (MZ) twins reared apart, (2) MZ twins reared together, (3) dizygotic (DZ) twins reared apart, and (4) DZ twins reared together. One issue is whether it is necessary to correct for gender before performing more complex genetic analyses. The data in Table 8.17 were presented for total cholesterol levels for MZ twins reared apart, by gender.
Table 8.17 Comparison of mean total cholesterol for MZ twins reared apart, by gender
Note: n = number of people (e.g., for males, 22 pairs of twins = 44 people) the cholesterol levels within each sample consist of independent observation.
Suppose we want to use the procedure in Problem 8.49 using a two-sided test. State the hypotheses being tested, and implement the method. Report a p-value.

The annual aggregate claim amount of an insurer follows a compound Poisson distribution with
parameter 1,000. Individual claim amounts follow a Gamma distribution with shape parameter
a = 750 and rate parameter λ = 0.25.
1. Generate 20,000 simulated aggregate claim values for the insurer, using a random
number generator seed of 955.Display the first five simulated claim values in your
answer script using the R function head().
2. Plot the empirical density function of the simulated aggregate claim values from
Question 1, setting the x-axis range from 2,600,000 to 3,300,000 and the y-axis range
from 0 to 0.0000045.
3. Suggest a suitable distribution, including its parameters, that approximates the
simulated aggregate claim values from Question 1.

Quality Control: A factory produces light bulbs with a 2% defect rate. If a random sample of 20 bulbs is tested, what is the probability that exactly 2 bulbs are defective? (hint: p=2% or 0.02; x =2, n=20; use the same logic for the following problems)
Marketing Campaign: A marketing company sends out 1,000 promotional emails. The probability of any email being opened is 0.15. What is the probability that exactly 150 emails will be opened? (hint: total emails or n=1000, x =150)
Customer Satisfaction: A survey shows that 70% of customers are satisfied with a new product. Out of 10 randomly selected customers, what is the probability that at least 8 are satisfied? (hint: One of the keyword in this question is “at least 8”, it is not “exactly 8”, the correct formula for this should be = 1- (binom.dist(7, 10, 0.7, TRUE)).
