Test Statistic

Critical Value

P-value

2a. Write the null and alternative hypotheses symbolically and identify which hypothesis is the claim. Then identify if the test is left-tailed, right-tailed, or two-tailed and explain why.

2b. Identify and explain which test statistic you will use for your hypothesis test: z or t? Find the value of the test statistic.

Provide your calculations in the cells designated to the right. Explain your answers below.

2c. What is the critical value? Describe the rejection region of this hypothesis test.

Provide your calculations in the cells designated to the right. Explain your answers below.
