Twelve percent of the world's population is left-handed. A researcher daims 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 1650 artists and finds that 10% of them are left-handed. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, wherep is the proportion of left-handed individuals in a random sample of 1650. (b) Find the standard deviation of p. (c) Compute an approximation for P(p s0.1), which is the probability that there will be 10% or fewer left-handed people in a random sample of 1650. Round your answer to four decimal places.
