Question 30
30. 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: Non-athletic women n = 30 F = 4.6 inches s=0.8 inches Athletic women m = 50 5.0 inches s=1.4 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. A) 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. B) Reject the null hypothesis; there is strong evidence to suggest that non-athletic women are more flexible, on average, than athletic women. C) Fail to reject the null hypothesis; there is strong evidence to suggest that non- athletic women are more flexible, on average, than athletic women. D)Reject the null hypothesis; there is strong evidence to suggest that athletic women are more flexible, on average, than non-athletic women.
