A particular lake is known to be one of the best places to catch a certain type of fish. In this table, x = number of fish caught in a 6-hour period. The percentage data are the percentages of fishermen who caught x fish in a 6-hour period while fishing from shore.
x 0 1 2 3 at least 4
% 42% 34% 12% 11% 1%
(b) Find the probability that a fisherman selected at random fishing from shore catches one or more fish in a 6-hour period. (Round your answer to two decimal places.)
(c) Find the probability that a fisherman selected at random fishing from shore catches two or more fish in a 6-hour period. (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 "at least 4" to 4). (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 "at least 4" to 4). (Round your answer to three decimal places.)
= fish
