What is the expected number of friends for whom addresses will be found? 1 (a) Make a histogram showing the probability of r - 0 to 6 friends for whom an address will be found, (b) Find the mean and standard deviation of this probability distribution. Suppose that you have the names of six friends for whom you have no addresses and decide to use Old Friends to track them. Old Friends claims to have a 70% success rate (Source: The Wall Street Journal). Private Investigation: Locating People Old Friends Information Service is a California company that is in the business of finding addresses of long-lost friends. What is the expected number of friends for whom addresses will be found?Ġ.20 0.15 0.10 0.05 0 1 2 3 4 5 6 Instructions: Follow the steps in this worksheet to graph and then compute u and a for the binomial probability distribution in Problem 13 in the textbook, which is reproduced here: 13.
