Find F stat find critical value Reject H0 or not?

Transcribed Image Text:Students in a business statistics course performed a completely randomized design to test the strength of four brands of trash bags. One-pound weights were- placed into a bag, one at a time, until the bag broke. A total of 24 bags, 6 for each brand, were used. The data in the accompanying table give the weight (in pounds) required to break the trash bags. Complete (a) through (d) below. E Click on the icon to view the data table. Click on the icon to view a partial table of critical values of F. Click on the icon to view a partial table of critical values of the Studentized Range, Q. A. No B. Yes O C. It is not appropriate to test which brands differ in mean strength. c. At the 0.05 level of significance, is there evidence of a difference in the variation in strength among the four brands of trash bags? Determine the hypotheses. Choose the correct answer below. O A. Ho o =03 = B. Ho: of = 03 = - H;: Not all o? are equal (where j = 1,2,..,4) Oc. Ho: o = o3 H,: Not all o? (where j= 1,2,...,6) O D. Ho: o =03 H;: 0} #o3 • · . • =o are equal Find the test statistic. FSTAT = (Round to two decimal places as needed.)
