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.
1. 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.
2. What is the probability that the sample proportion will be within +-.03 of the population proportion.
1. Since the sample size of 150 is large enough, by the central limit theorem, the sampling ...
The solution gives detailed steps on calculating the probability based on the sampling distribution of proportion. All formula and calculations are shown and explained.
