Your answer is incorrect. The mean daily rainfall in Los Angeles in December is 0.05 inches with a standard deviation of 0.02 inches. What is the BB probability that the total rainfall in Los Angeles for 35 randomly selected December days (possibly over several years) will exceed 2 inches? Carry your intermediate computations to at least four decimal places. Report your result to at least three decimal places.

Suppose the yearly rainfall totals for a some city follow a normal distribution, with mean of 18 inches and standard deviation of 6 inches. For a randomly selected year, what is the probability, P, that total rainfall will be in each of the following intervals? (Round all answers to four decimal places.) (a) Less than 12 inches.P = ?(b) Greater than 27 inches.P = ?(c) Between 12 and 24 inches.P = ?(d) Greater than 35 inches.P = ?

In a murder trial in Los Angeles, a shoe expert stated that the range of heights of men with a size 12 shoe is 70 inches to 77 inches. Suppose the heights of all men wearing size 12 shoes are normally distributed with a mean of 73.5 inches and a standard deviation of 4.0 inches. What is the probability that a randomly selected man who wears a size 12 shoe (Do not round the z values. Use a statistical software...

Central limit theorem: Sample mean A worldwide organization of academics claims that the mean IQ score of its members is 115, with a standard deviation of 16. A randomly selected group of 35 members of this organization is tested, and the results reveal that the mean IQ score in this sample is 114.4. If the organization's claim is correct, what is the probability of having a sample mean of 114.4 or less for a random sample of this size? Carry...
