Question 2

The manager of University Credit Union (UCU) is concerned about checking account transaction discrepancies. Customers are bringing transaction errors to the attention of the bank's staff several months after they occur. The manager would like to know what proportion of his customers balance their checking accounts within 30 days of receiving a transaction statement from the bank. Using random sampling, 400 checking account customers are contacted by telephone and asked if they routinely balance their accounts within 30 days of receiving a statement. 271 of the 400 customers respond Yes.
 a. Develop a 95 confidence interval estimate for the proportion of the population of checking account customers at UCU who routinely balance their accounts in a timely manner.
  b. Suppose UCU wants a 95 confidence interval estimate of the population proportion with a margin of error of E = .025 . What sample size is needed?
