Suppose that we are to conduct the following hypothesis test: H0: =940 H1: >940 Suppose that you also know that =170, n=80, x=970.6, and take

Suppose that we are to conduct the following hypothesis test: 

H0: μ=940

H1: μ>940 

Suppose that you also know that σ=170, n=80, x¯=970.6, and take α=0.05. 

Draw the sampling distribution, and use it to determine each of the following:

 A. The value of the standardized test statistic: 

Note: For the next part, your answer should use interval notation. An answer of the form (−∞,a) is expressed (-infty, a), an answer of the form (b,∞) is expressed (b, infty), and an answer of the form (−∞,a)∪(b,∞) is expressed (-infty, a)U(b, infty). 

B. The rejection region for the standardized test statistic: 

C. The p-value is 

D. Your decision for the hypothesis test:

    A. Reject H1.

    B. Reject H0. 

    C. Do Not Reject H0.

    D. Do Not Reject H1.
