Two sample Dependent t-test (testing the difference between two related samples) In industrial settings, alternative methods often exist for measuring variables of interest. There are two methods, one named "in-line" and one named "analytical lab", both methods are measuring the same variable The data shown in the accompanying table represent measurements in-line that were collected from an analyser during the production process and from an analytical lab. Complete all parts Click the icon to view the data table. a. At the 0.10 level of significance, is there evidence of a difference in the mean measurements in-line and from an analytical lab? Let u, be the mean measurements in-line and let u2 be the mean measurements from an analytical lab. State the null and alternative hypotheses for testing the difference in the two methods' measurements. Choose the correct answer below. O A. Ho: HD = 0 (where HD = H1 / H2) OB. Ho: HD = 0 (where HD = M1 - H2) H1 : HD 20 H1 : HD 0 H1 : HD $ 0 The test statistic is t =. (Round to two decimal places as needed.) The p-value is. (Round to three decimal places as needed.) Since the p-value is the value of a, There is V evidence of a difference in the mean measurements.
