Consider the following hypothesis statement using a = 0.10 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 = 0 X, = 14.8 X7 = 13.0 H1 : 1 1 - 12 = 0 Sy = 2.7 S2 = 3.2 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, do not reject the null hypothesis. O B. Since the p-value is not less than the significance level, reject the null hypothesis. O C. Since the p-value is less than the significance level, reject the null hypothesis. O D. Since the p-value is less than the significance level, do not reject the null hypothesis
