A researcher determines a sample of size (n) 100 is necessary to estimate a population mean with 95 confidence
  (z = 2). The calculation of sample size required that he estimate the population standard deviation since it was
  unknown, and he estimated it as 150 . The 100 observations produced a sample mean and a sample standard
  deviation
  The resulting confidence interval is
 a. 970 <  < 1030.
  b. 996 <  < 1004.
  c. 997 <  < 1003.
  d. 960 <  < 1040.
