Consider the following hypothesis test: Ho: μ > 45 Ha: μ < 45 A sample of 36 is used. Identify the p-value and state your conclusion for each of the following sample results. Use α = 0.01. a. With = 44 and s=5.2, the p-value is between 0.005 and 0.01 Can it be concluded that the population mean is less than 45 ? No b. With = 43 and s = 4.6, the p-value is between 0.01 and 0.025 Can it be concluded that the population mean is less than 45? Yes c. With = 46 and s=5, the p-value is between 0.01 and 0.025 Can it be concluded that the population mean is less than 45? Yes
