Hypothesis Testing and Statistical Calculations
1. HO: µ = 70 H1: µ > 70 ? = 20, n = 100, xbar = 80, ? = .01 a) calculate the value of the test statistic b) set up the rejection region. c) determine the p-value d) interpret the results attach file please 2. Draw the operating characteristic curve for n = 10, 50, and 100 for the following test: Ho: ? = 400
