Determine Whether the Hypothesis Test Involves a Sampling Distribution of Means

Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t
distribution, or neither.
-Claim: $\mu = 981$ . Sample data: $\mathrm { n } = 23 , \mathrm { x } = 912 , \mathrm {~s} = 30$ . The sample data appear to come from a normally distributed population with $\sigma = 30$ .

A) Normal
B) Neither
C) Student t
