Chapter 11.1, Problem 8E
The paper “If It’s Hard to Read, It’s Hard to Do” (Psychological Science [2008]: 986–988) described an interesting study of how people perceive the effort required to do certain tasks. Each of 20 students was randomly assigned to one of two groups. One group was given instructions for an exercise routine that were printed in an easy-to-read font (Arial). The other group received the same set of instructions, but printed in a font that is considered difficult to read (Brush).
After reading the instructions, subjects estimated the time (in minutes) they thought it would take to complete the exercise routine. Summary statistics are given below.

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.
4. Generate 20,000 values from your suggested distribution in Question 3 using a random
number generator seed of 955. Use the R function head() to display the first five

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)).

Let Y denote whether a subject convicted of murder received the death penalty (1=yes), for the defendant's race h (h1, black; h = 2, white), victim's race i (i = 1, black; i = 2, white), and number of additional factors j (j = 0, 1, 2).
