A farmer looks at the latest Almanac and finds that there is a 15% chance for a long hot summer and a 10% chance for a wet summer. A nice average summer will provide the farmer with a profit
of $100,000 on his harvest. He knows that a hot summer will dry up his crops and his harvest will
only be $3.000. He also knows that a wet summer will rot his crops and his harvest will only be
$5.000. Find the expected value of the farmer's harvest?

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
