(1 point) Use the following information to answer the exercises: A physics professor wants to know what percent of physics majors will spend the next several years doing post-graduate research. He has the following probability distribution.
| ?X | 1 | 2 | 3 | 4 | 5 | 6 |
| ?(?)P(X) | 0.16 | 0.19 | 0.11 | 0.12 | 0.05 | 0.37 |
Find the probability that a physics major will do post-graduate research for four years.
Find the probability that a physics major will do post-graduate research for at most three years.
On average, how many years would you expect a physics major to spend doing post-graduate research?

Use Table 8.1, a computer, or a calculator to answer the following. Suppose a candidate for public office is favored by only 47% of the voters. If a sample survey randomly selects 2,500 voters, the percentage in the sample who favor the candidate can be thought of as a measurement from a normal curve with a mean of 47% and a standard deviation of 1%. Based on this information, how often (as a %) would such a survey show that...
