Question:
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.
