A waiter believes the distribution of his tips has a model that is slightly skewed to the right, with a mean of $9.70 and a standard deviation of $4.60. He usually waits on about 40 parties over a weekend of work. a) Estimate the probability that he will earn at least $450. b) How much does he earn on the best 1% of such weekends? a) P(tips from 40 parties > $450) = (Round to four decimal places as needed.)
