Question 1063029: Grip and Leg Strength. 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.
Male

part A Question.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.

a. At the 5% significance level, do the data provide sufficient evidence to conclude that mean right-leg strength of males exceeds that of females? (Note: . x1 = 2127, s1 = 513,. x2 = 1843, and s2 = 446.)
b. Estimate the P-value of the hypothesis test, and use that estimate and table 9.12
P-value
P >0.10
0.05 0.01 P ≤ 0.01
Evidence against H0
Weak or none
Moderate
Strong
Very strong
assess the strength of the evidence against the null hypothesis.

part B Question.Determine a 90% confidence interval for the difference between the mean right-leg strengths of males and females. Interpret your result.
