With reference to Exercise 40, what can we say with 95% confidence about the maximum error if we use the observed sample proportion as an estimate of the corresponding true proportion?
Exercise 40
In a random sample of 250 television viewers in a large city, 190 had seen a certain controversial program. Construct a 99% confidence interval for the corresponding true proportion using
(a) the large-sample confidence-interval formula of Theorem 6;
(b) the confidence limits of Exercise 11
Theorem 6
Exercise 11
By solving
