A manufacturer of mountaineering equipment produces traditional three-strand climbing rope on two separate production lines, line 1 and line 2. The manufacturer regularly tests the tensile strength of its ropes by randomly selecting ropes from production and subjecting them to various tests. The results from the most recent random sample of ropes are shown below. Assuming the population of tensile strengths for each line is approximately normally distributed with equal Line 1 Line 2 variances, can the manufacturer conclude there is a difference between the mean tensile strengths of ropes X1 = 7,204 lb X2 = 7,136 lb produced on the two lines? Conduct the appropriate hypothesis test at the 0.10 level of significance. S1 = 430 S2 = 415 n1 = 15 n2 = 30 . . . . . What are the appropriate hypotheses to test? OA. HO: My - H2 # 0 OB. HO: H1 - H250 O C. Ho: H1 - H2 >0 HA: H1 - H2=0 HA: H1 - 12 >0 HA: H1 - H2 SO OD. HO: H1 - H2 OB. t Calculate the value of the test statistic. t= (Round to four decimal places as needed.) Since the test statistic in the rejection region the null hypothesis. There is evidence to conclude that the two population means are different
