Question 16 5 pts In an experiment to determine whether there is a systematic difference between the weights obtained with two different mass balances, six specimens were weighed, in grams, on each balance. The following data were obtained: Specimen A B 13.76 13.74 12.47 12.45 10.09 10.08 autWN 8.91 8.92 13.57 13.54 12.74 12.75 Can you conclude that the mean weight differs between the two balances? 1). State the null and alternative hypotheses. ii). Compute the test statistic. iii). State a conclusion using the a = 0.05 level of significance. O i). Ho: Hd = 0, H:Hd * 0 i). 1.464 iii). Do not reject Ho. There is insufficient evidence to conclude that the meandifference differs from zero. O i). Ho: Hd = 0, H1: Hd * 0 ii). 1.680 iii). Do not reject Ho. There is insufficient evidence to conclude that the meandifference differs from zero. O i). Ho: Hd = 0, H: ud # 0 1). 1.464 iii). Reject Ho. The mean difference appears to differ from zero. O i). Ho: Md = 0, H1: Hd * 0 i). 1.680 iii). Reject Ho. The mean difference appears to differ from zero
