Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution. 18) A savings and loan association needs information concerning the checking account balances of its local customers. A random sample of 14 accounts was checked and yielded a mean balance of $664.14 and a standard deviation of $297.29. Find a 98% confidence interval for the true mean checking account balance for local customers. A) $455.65 <μ< $872.63 c) $492.52 << $835.76 B) $453.59 <μ< $874.69 D) $493.71 < u< $834.57 Use the given information to find the P-value and state the conclusion of the hypothesis test.
