The probability distribution shows the probability of each possible outcome, zero through 15. That is, if you were to ask a total of 15 people to sample both Coke and Pepsi, the probability distribution you have created will show you the chance that any specific number of people will guess correctly. Print out the distribution and then respond manually to the following questions:
1. Is the distribution collectively exhaustive? What is the evidence for your answer?

After years of rapid growth, illegal immigration into the United States has declined, perhaps owing to the recession and increased border enforcement by the United States (Los Angeles Times, September 1, 2010). While its share has declined, California still accounts for 29% of the nation’s estimated 11.9 million undocumented immigrants. Use Table 1. |
| a. |
In a sample of 40 illegal immigrants, what is the probability that more than 23% live in California? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.) |
