Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither.
-Claim: $\mu = 78$. Sample data: $n = 24 , \bar { x } = 101 , s = 15.3$. The sample data appear to come from a population with a distribution that is very far from normal, and $\sigma$ is unknown.
A) Normal
B) Neither
C) Student t

Question

The sample size is less than 30, the population distribution is not normal, and the population standard deviation is unknown, so neither the normal nor the Student t distribution is appropriate.
