The proportion of individuals insured by the All-Driver Automobile Insurance Company who received at least one traffic ticket during a five-year period is .15. Use z-table. a. Show the sampling distribution of p, if a random sample of 150 insured individuals is used to estimate the proportion having received at least one ticket (to 4 decimals). Can assume to be normally distributed because np>=5 and n(1-p)>=5 E(p) = 0.15 standard error of the proportion (op) = 0.0292 b. What is the probability that the sample proportion will be within +/- .03 of the population proportion (to 3 decimals)? (Round z value in intermediate calculations to 2 decimal places.)
