A waiter believes the distribution of his tips has a model that is slightly skewed to the right, with a mean of $9.60 and a standard deviation of $4.70. He usually waits on about 50 parties over a weekend of work. a) Estimate the probability that he will earn at least $500. b) How much does he earn on the best 10% of such weekends? a) P(tips from 50 parties> $500)= (Round to four decimal places as needed.)

a. The mean of this distribution is b. The standard deviation is c. The probability that the the child will be older than 5 years old?

A waiterbelieves the distribution of his tips has a model that is slightly skewed to the left​, with a mean of ​$8.60 and a standard deviation of $4.20.

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 254 feet and a standard deviation of 43 feet. Use your graphing calculator to answer the following questions. Write your answers in percent form. Round your answers to the nearest tenth of a percent. a) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 204 feet? P(fewer than 204 feet) = % b) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled more than 216 feet? P(more than 216 feet) =
