A researcher wants to know whether athletic women are more flexible than non-athletic women For this experiment, a woman who exercised vigorously at least four times per week was considered "athletic". Flexibility is measured in inches on a sit & reach box. A researcher tested his claim using the following summary statistics. Athletic women Non-athletic women n = 50 n=30 X=4.6 inches s=0.8 inches Assume that all conditions for testing have been met t = 1.626; p = 0.057, At the 1% significance level, state your decision regarding the null hypothesis and your conclusion about the original claim 5.0 inches s=1.4 inches C OA. Fail to reject the null hypothesis, there is not strong enough evidence to suggest that athletic women are more flexible, on average, than non-athletic women. OB. Fail to reject the null hypothesis, there is strong evidence to suggest that non-athletic women are more flexible, on average, than athletic women. OC. Reject the null hypothesis, there is strong evidence to suggest that non-athletic women are more flexible, on average, than athletic women. OD. Reject the null hypothesis; there is strong evidence to suggest that athletic women are more flexible, on average, than non-athletic women
