Consider the following hypothesis statement using a = 0.01 and data from two independent samples. Assume the population variances are equal and the populations are normally distributed. Complete parts a and b. Ho: H1 - H2 $ 12 *1 = 82.3 X2 =58.5 H1: H1 - 2 > 12 51 = 19.1 S2 = 19.9 n1 = 20 n2 = 22 a. Calculate the appropriate test statistic and interpret the result. The test statistic is (Round to two decimal places as needed.) The critical value(s) is(are) | (Round to two decimal places as needed. Use a comma to separate answers as needed.) Because the test statistic the null hypothesis. b. Identify the p-value from part a and interpret the result. The p-value is. (Round to three decimal places as needed.) Interpret the result. Choose the correct answer below. O A. Since the p-value is not less than the significance level, reject the null hypothesis. O B. Since the p-value is not less than the significance level, do not reject the null hypothesis. Vi Vi More Click to select your answer(s)
