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 * = 5.0 inches s=1.4 inches 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. O A. Fail to reject the null hypothesis; there is strong evidence to suggest that non-athletic women are more flexible, on average, than athletic women. O B. 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. O C. Reject the null hypothesis; there is strong evidence to suggest that non-athletic women are more flexible, on average, than athletic women. O D. Reject the null hypothesis; there is strong evidence to suggest that athletic women are more flexible, on average, than non-athletic women.
