Chapter 9 and 10 Assignment: Problem 7 (1 point) Suppose that we are to conduct the following hypothesis test: H0:μ=1090H1:μ>1090 Suppose that you also know that σ=190,n=80,xˉ=1120.4, and take α=0.1. 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) (b, infty). B. The rejection region for the standardized test statistic: C. The p-value is D. Your decision for the hypothesis test: A. Do Not Reject H0. B. Reject H1. C. Reject H0. D. Do Not Reject H1.
