Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither.
-Claim: $\mu = 959$. Sample data: $n = 25 , \bar{x} = 951 , s = 25$. The sample data appear to come from a normally distributed population with $\sigma = 28$.
A) Normal
B) Neither
C) Student $t$

Question

Quizplus · Accepted Answer

Since the population standard deviation ($\sigma$) is known and the sample data come from a normally distributed population, the sampling distribution of means is a normal distribution.
