The proportion of Canadians with green eyes is 0.5. As part of a study of the genetic basis for skin sensitivity to sunlight, a research term collects a simple random sample of 350 Canadians. Answer the following questions to 4 places past the decimal. a) How many people in the sample would you expect to have green eyes? |0.0014 Incorrect. Tries 3/3 Previous Tries b) What is the standard deviation of the sample proportion? (Use the normal approximation from now on). Submit Answer | Tries 0/3 c) What is the probability that the sample proportion will exceed 0.5267? Submit Answer Tries 0/3Question2: A city council is considering drafting legislation related to the exclusion of renters with children. Since implementation will be expensive, they will only consider proceeding if the true proportion of apartments that prohibit children is more than 75 percent. Suppose that out of 125 sampled apartments, 102 exclude renters with children. 1) What is the observed proportion of apartments which exclude renters with children? O 0.750 O 0.816 O 0.184 1.226 Unknown Submit Answer Incorrect. Tries 1/2 Previous Tries 2) What is the true proportion of apartments which exclude renters with children? O 0.750 O 0.816 O 0.184 O 1.226 O Unknown Submit Answer Tries 0/2 3) Compute the standard error of the observed proportion.
