The sitting height of a person is the vertical distance between the sitting surface and the top of the head. The accompanying table lists sitting heights (mm) of randomly selected U.S. Army personnel collected as part of a large reputable study. Using the data with a 0.05 significance level, what do you conclude? iClick the icon to view the sitting height data. First test for an interaction between the two factors. Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: Sitting heights are not affected by gender. H₁: Sitting heights are affected by gender. OB. Ho: Sitting heights are not affected by handedness. H₁: Sitting heights are affected by handedness. OC. Ho: Sitting heights are not affected by an interaction between gender and handedness. H₁: Sitting heights are affected by an interaction between gender and handedness. O D. Ho: Sitting heights are affected by an interaction between gender and handedness. H₁: Sitting heights are not affected by an interaction between gender and handedness. Determine the test statistic. The test statistic is (Round to two decimal places as needed.) Determine the P-value. Sitting Height Data Female Male Right-Handed 857 879 875 786 898 944 909 901 912 947 Print Left-Handed 871 859 885 847 812 1001 916 1030 915 977 Done The P-value is. (Round to three decimal places as needed.) Determine the proper conclusion at the 0.05 significance level. Choose the correct answer below. OA. Fail to reject Ho. There is insufficient evidence to support the alternative hypothesis. There appears to be an interaction between gender and handedness. X
