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. Test the researcher's claim using the summary statistics below. Assume that all conditions for testing have been met. Report the test statistic and p-value. At the 1% significance level, state your decision regarding the null hypothesis and your conclusion about the original claim. Round all values to three decimal places. Click the icon to view the summary statistics. O A. t= 1.623; p = 0.055; Fail to reject the null hypothesis; there is not strong evidence to suggest that athletic women are more flexible than non-athletic women. O B. t= 1.623; p= 0.108; Reject the null hypothesis; there is not strong evidence to suggest that athletic women are more flexible than non-athletic women. Oc. t= - 1.623; p= 0.054; Reject the null hypothesis; there is strong evidence to suggest that athletic women are more flexible than non-athletic women. O D. t= - 1.623; p = 0.108; Reject the null hypothesis; there is strong evidence to suggest that athletic women are more flexible than non-athletic women.
