Which of the following does not need to be known in order to compute the $p$-value in a hypothesis test?

A candy manufacturer seeking to minimize the variation in weights of their candies claims to produce candies with a standard deviation less than $0.300$ g. Write the null and alternative hypotheses.

Which of the following is a correct interpretation of a $p$-value that is not very small in the context of hypothesis testing?

A null hypothesis can only be rejected at the $5\%$ significance level if and only if which of the following is true?

In a certain hypothesis test, $H_0:p=0.4$, $H_a:p$ < $0.4$. You collect a sample and calculate a test statistic $z=-1.32$. Find the $P$-value.

Suppose you conduct a hypothesis test and your p-value is equal to $0.002$. What can you conclude if your significance level is $0.05$?

Which of the following is not a conclusion of the central limit theorem?
