(1) A recent survey of 1030 U.S. adults selected at random showed that 645 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige. (Enter a number.)

(2) A particular lake is known to be one of the best places to catch a certain type of fish. In this table,x= numberof fish caught in a6-hourperiod. The percentage data are the percentages of fishermen who caughtxfishin a6-hourperiod while fishing from shore.

x	0	1	2	3	4 or more
%	43%	35%	15%	6%	1%

(c) Find the probability that a fisherman selected at random fishing from shore catches two or more fish in a 6-hour period. (Enter a number. Round your answer to two decimal places.) (d) Compute, the expected value of the number of fish caught per fisherman in a 6-hour period (round 4 or more to 4). (Enter a number. Round your answer to two decimal places.) = fish (e) Compute, the standard deviation of the number of fish caught per fisherman in a 6-hour period (round 4 or more to 4). (Enter a number. Round your answer to three decimal places.) = fish
