Question

In the paper, "Sex Differences in Static Strength and Fatigability in Three Different Muscle Groups" (Research Quarterly for Exercise and Sport, Vol. 61(3), pp. 238-242), J. Misner et al. published results of a study on grip and leg strength of males and females. The following data, in newtons, is based on their measurements of right-leg strength.
Preliminary data analyses indicate that you can reasonably presume leg strength is normally distributed for both males and females and that the standard deviations of leg strength are approximately equal. At the 5% significance level, do the data provide sufficient evidence to conclude that mean right-leg strength of males exceeds that of females?
