13 Homework Question 11, 13.7.45-T HW Score: 62.63%, 9.4 of 15 points Part 5 of 5 Points: 0.29 of 1 Save A researcher developed a regression model to predict the tear rating of a bag of coffee based on the plate gap in bag-sealing equipment. Data were collected on 30 bags in which the plate gap was varied. An analysis of variance from the regression showed that b, = 0.7501 and Sp = 0.2075. a. At the 0.05 level of significance, is there evidence of a linear relationship between the plate gap of the bag-sealing machine and the tear rating of a bag of coffee? b. Construct a 95% confidence interval estimate of the population slope, By. a. Determine the hypotheses for the test. Choose the correct answer below. O A. Ho: Bo = 0 B. Ho: B1 = 0 O C. Ho: Bozo Hy : Bo # 0 H1 : B1 0 Hy : Bo O Hy : By O Compute the test statistic. The test statistic is 3.61 . (Round to two decimal places as needed.) Determine the critical value (s). The critical value(s) is(are) - 2.05,2.05 (Use a comma to separate answers as needed. Round to two decimal places as needed.) Reach a decision. Reject Ho. There is sufficient evidence at the 0.05 level of significance to conclude that there is a linear relationship between the plate gap of the bag-sealing machine and the tear rating of a bag of coffee. b. The 95% confidence interval is spy s (Round to four decimal places as needed.) w an example Get more help - Clear all Check
