Ten 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 900 artists and finds that 11% of them are left-handed. a. Find the mean of ê, where is the proportion of left-handed individuals in a random sample of 900. b. Find the standard deviation of p. c. Compute an approximation for p (p20.11), which is the probability that there will be 11% or more left-handed people in a random sample of 900. Round your answer to four decimal places. (If necessary, consult a list of formulas.) X 5 ?
