A hosptial has 500 patients - I sample 100 regarding opinion on quality of care - 74 are favorable. Data is assumed to be normally distributed. Use this sample to predict the population proportional and to do so with 98% confidence- (finite correct factor).
a. what is the lower limit for this 98% confidence interval
b. what is the upper limit fo rthis 98% confidence interval
c. what is the upper limit for a 99% confidence interval?
d. what is the upper limit for #15 if the sample size is 64?

Favourable = 74%
Unfavourable = 26%
Sample Size = 100
Std Dev = sqrt(npq)
Z value for 98% Confidence = ...
