(b)
What sampling distribution will you use? Explain the rationale for your choice of sampling distribution.
We'll use the standard normal, since we assume that x has a normal distribution with known 𝜎.We'll use the standard normal, since we assume that x has a normal distribution with unknown 𝜎. We'll use the Student's t, since we assume that x has a normal distribution with known 𝜎.We'll use the Student's t, since n is large with unknown 𝜎.
Compute the z value of the sample test statistic. (Round your answer to two decimal places.)
(c)
Find (or estimate) the P-value. (Round your answer to four decimal places.)
P-value =
