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 samplingdistribution of p if a random sampleof 150 insured individuals is used to estimate the proportion having received at least one ticket.
2. What is the probabilitythat 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.
