Points: 0.5 of 1 Save - K A random sample of male

Points: 0.5 of 1 Save - K A random sample of male college baseball players and a random sample of male college soccer players were obtained independently and weighed. The accompanying table shows the unstacked weights (in pounds). The distributions of both data sets suggest that the population distributions are roughly Normal. Using a two-tailed test with a significance level of 0.05, the null hypothesis that the mean weights of soccer and baseball players are equal is rejected. Complete parts (a) through (c) below.

If a 95% confidence interval for the difference between means was found, would it capture 0? Exp OA. The 95% interval would capture 0, because the hypothesis that the mean weights are the sar OB. The 95% interval would not capture 0, because there appears to be a difference between the C. The 95% interval would not capture 0, because the hypothesis that the mean weights are the OD. The 95% interval would capture 0, because there does not appear to be a difference betweer b. If a 90% confidence interval for the difference between means was found, would it capture 0? Exp No, because a 90% interval is narrower than a 95% interval and centered at the same value, a c. Find a 95% confidence interval for the difference between means, and explain what it shows. The 95% confidence interval for the difference between means (Baseball minus Soccer) is ( (Round to two decimal places as needed. Use ascending order.) 191 Print Done + B Clear all Check answer c
