Question: Refer to Exercise 12.26.
- Find the margin of error for the estimate of p.
- Obtain a sample size that will ensure a margin of error of at most 0.02 for a 95% confidence interval without making a guess for the observed value of .
- Find a 95% confidence interval for p if, for a sample of size determined in par (b), 63% of those sampled drink alcoholic beverages.
- Determine the margin of error for the estimate in part (c) and compare it to the margin of error specified in par (b).
