(06.07 LC) The mean and standard deviation for number of battery crimes in the U.S. from 1985 to 2000 are x̄ = 326,845 and sx = 27,569. The mean and standard deviation for number of property crimes in the U.S. for the same time period are ȳ = 634,235 and sy = 42,268. The correlation coefficient is r = 0.92. Find the equation for the least-squares regression line for number of property crimes compared with number of battery crimes. (4 points)

(04.03 MC) The probability that Barry Bonds hits a home run on any given at-bat is 0.16, and each at-bat is independent. Part A: What is the probability that the next home run will be on his fifth at-bat? (5 points) Part B: What is the expected number of at-bats until the next home run? (5 points) (10 points)
