Question

Suppose that we are to conduct the following hypothesis test: H0: μ = 1080 ,  H1:μ >1080

Suppose that you also know that σ=240, n=100, x¯=1125.6, and take α=0.005. Draw the sampling distribution, and use it to determine each of the following:

A. The value of the standardized test statistic:

1.9 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 0.0287 D. Your decision for the hypothesis test: A. Do Not Reject H0. B. Reject H1. C. Reject H0. D. Do Not Reject H1.
