A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x overbarx, is found to be 19.3, and the sample standard deviation, s, is found to be 5.6 If the sample size is
2323,
what conditions must be satisfied to compute the confidence interval?
A.
Since the sample size is suitably large, the population need not be normally distributed, but it still should not contain any outliers.
B.
The sample data must come from a population that is normally distributed with no outliers.
C.
The sample must come from a population that is normally distributed and the sample size must be large.
