# Question: Use the following sample information to calculate the confidence interval

Use the following sample information to calculate the confidence interval to estimate the population proportion. Let x be the number of items in the sample having the characteristic of interest.

a. n = 116 and x = 57,with 99% confidence

b. n = 800 and x = 479,with 97% confidence

c. n = 240 and x = 106,with 85% confidence

d. n = 60 and x = 21,with 90% confidence
