A random sample of elementary school children in New York state is to be selected to estimate the proportion p who have received a medical examination during the past year. A random sample of 200 elementary school children indicated that 18 of them had received a medical examination in the past year. 14. Find point estimate for p and also construct a 95% confidence interval for p. (a) .09, (.04, .14) (b) .9, (.01, .17) (c) 200, (.01, .17) (d) 200, (.05.13) (e) .09, (.05, .13). 15. Using the information from the above sample, find the minimum sample size needed to estimate the population proportion p with 99% confidence. The estimate must be accurate to within .02 of p. (a) n = 1701 (b) n = 4145 (c) n = 1358 (d) n = 2936 (e) n = 2401.
