Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t
distribution, or neither.
-Claim: $\mu = 107$. Sample data: $\mathrm { n } = 17 , \bar { x } = 101 , \mathrm {~s} = 15.1$. The sample data appear to come from a normally distributed population with unknown $\mu$ and $\sigma$.
A) Normal
B) Student t
C) Neither
