When a fisherman catches a fish (either young or adult), it is a young one with a probability of 0.37 and it is returned to the water. Onthe other hand, an adult fish is kept to be eaten later. (Round your answers to 4 decimal places, if needed.)(a) What is the expected number of fish caught by the fisherman before an adult fish is caught? The standard deviation?Expected number:Standard deviation:(b) What is the probability that the 6th fish caught is the first young fish?Answer:Suppose that the fisherman wants three fish to eat for lunch.(c) What is the probability that the first time the fisherman can stop for lunch is immediately after the 6th fish has been caught?Answer:(d) What is the expected number of fish caught so that there are sufficient fish for lunch? The standard deviation?Expected number:Standard deviation:(e) If the fisherman catches eight fish, what is the probability that there are sufficient fish for lunch?Answer:

Empirical research on stock market data for two consecutive trading days indicates that 60% of the stocks that went up on the first day also went up on the second day. Yesterday, 600 stocks went up. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p gives the proportion of the 600 stocks that went up yesterday that will go up today. (b) Find the standard deviation of p. (c) Compute an approximation for P(p <0.58), which is the probability that fewer than 58% of the stocks that went up yesterday will go up again today. Round your answer to four decimal places.
