According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard deviation of 0.05 inches. What is the probability that the mean daily precipitation will be 0.09 inches or more for a random sample of 40 November days (taken over many years)? Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places. X 5 ?Sixteen percent of the world's population is left-handed. A researcher claims that left-handed individuals are more creative than those who aren't left-handed. In order to support his claim, he takes a sample of 2100 artists and finds that 17% of them are left-handed. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of left-handed individuals in a random sample of 2100. X 5 ? 0 (b) Find the standard deviation of p. (c) Compute an approximation for P(p
