Apopulation of 300 payments purportedly made for power wheelchairs was isolated and a simple random sample of 30 selected. after examining documentation, the claims reviewer concluded that none of the sampled payments was justified (none of the beneficiaries ever received a wheel chair); therefore d=30 where d is the number of sampled claims that should have been denied. a. (5) compute a 95% confidence interval for the population p, the proportion of all 300 claims that should have been denied, using the textbook (“wald”) formula. is there anything about this interval that bothers you? b. (5) use the r function get. hyperci in the provided r workspace hyperbounds to compute a conservative 95% confidence interval for p.
