Textbook Question
Chapter 12, Problem 10CRE
Lottery: Goodness-of-Fit The bars in the histogram included with Exercise 9 depict these frequencies: 21, 19, 15, 18, 24, 18,16,24,30, and 15. Test the claim that the digits are selected from a population in which the digits arc all equally likely. Is there a problem with the lottery?
9. Lottery: Interpreting a Graph Shown below is a histogram of digits selected in California’s Win 4 lottery. Each drawing involves the random selection (with replacement) of four digits between 0 and 9 inclusive.
- a. If the lottery works correctly, what should be the shape of the histogram in the long run? Does the histogram shown here depict the expected distribution?
- b. Does the display depict a
normal distribution ? Why or why not?

Based on a poll, among adults who regret getting tattoos, 28%
say that they were too young when they got their tattoos.
Assume that six adults who regret getting tattoos are
randomly selected, and find the indicated probability. Complete
parts (a) through (d) below.
a. Find the probability that none of the selected adults say that
they were too young to get tattoos.

Since no existing treatment exists, they have planned a one-armstudy. They wish to test whether the success rate of the drug is better than 50%, whichthey have defined as the null success rate. Preliminary testing has estimated the successrate of the drug at 55%. The investigators are eager to get the drug into production andwould like to plan for 9 interim analyses (10 analyzes in total) of the data.
