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 - 142 $12 X1 = 70 8 X2 = 56.2 H1 Py - 12 > 12 $1 = 16.1 $2 = 18.4 n1 = 19 12 =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
