Question

Required Information The following output (from R) presents the results of a hypothesis test for a population mean ?. One-sample z-Test data: x z = 1.9649, p-value = 0.02471 alternative hypothesis: true mean is greater than 25 95 percent confidence interval: 25 25.037 NA sample estimates: mean of x 26.537 Assume the population standard deviation is ? = 5.5311 and the sample size is n = 50. Use these values, along with other values in the output, to compute the P-value for the test of H?: ? ? 25.2 versus H?: ? > 25.2. (Round your answer to four decimal places.) P-value: ____
