(d) Compute the expected age u of a British nurse CUIMUIIp Nightingale. (e) Compute the standard deviation o for ages of nurses shown in the distribution. 60 years of age t0 Plorence Fishing: Trout The following data are based on information taken from Daily Creel Summary, published by the Paiute Indian Nation, Pyramid Lake, Nevada. Movie stars and U.S. presidents have fished Pyranmid Lake. It is one of the best places in the lower 48 states to catch trophy cutthroat trout. In this table, x = number of fish caught in a 6-hour period. The percentage data are the percentages of fishermen who catch x fish in a 6-hour period while fishing from shore. 1 abi 2 3. 4 or more 44% 36% 15% 4% 1% (a) Convert the percentages to probabilities and make a histogram of the probability distribution. (b) Find the probability that a fisherman selected at random fishing from shore catches one or more fish in a 6-hour period. (c) Find the probability that a fisherman selected at random fishing from shore catches two or more fish in a 6-hour period. (d) Compute u, the expected value of the number of fish caught per fisher- man in a 6-hour period (round 4 or more to 4). (e) Compute o, the standard deviation of the number of fish caught per fisher- man in a 6-hour period (round 4 or more to 4).
