A random sample of 44 senior citizens was polled and it was found that 22 would use such aservice.a. Let p represent the proportion of all senior citizens in the region who would utilize the mobile medicalcheck-up program. Find a point estimate for p. (Round result to 3 decimal places.)b. Find a 95% confidence interval for p. (Round results to 3 decimal places.)? ♥<c. The Rogers County Director tasks you with doing a larger study, to develop a more precise estimate. Thedirector would like an estimate for the proportion of retired people who would use the mobile medicalcheck-up program that is within 5% of the population percentage, with 95% confidence. Using the originalstudy (described above) as a preliminary estimate for the population proportion p, what is the minimumsample size required to fulfill the director's request?Minimum sample size: n =
