question 2

Essay

To investigate the effect of sleep on basal metabolism, seven students who averaged seven or more hours of sleep a night (Group A), and five students who averaged less than seven hours of sleep a night (Group B), were examined and their basal metabolism recorded as shown below. Since it was not clear whether the assumptions for a t test were valid, the researcher decided to employ nonparametric methods. Use the Wilcoxon rank sum test to determine whether the metabolism measurements for Group A are significantly higher than those of Group B. Use = 0.05.
