Forty seven subjects who were at least 20% overweight took nart in a group support program for 10 weeks, The weight of each subject was recorded at the beginning of the program and at the end of the program. A 95% confidence inkerval for the mean difference in weight loss (before - after) was found to be (12. 18) pounds. Could this information be used to conclude whether we would have rejected the null hypothesis that the program had no effect on average weight loss for people at least 20% over weight, using a significance level of 0.05? O No, there is no relationship between confidence intervals and hypothesis tests O Yes, because 20% is not contained in the interval. O Yes, because the confidence interval does not include zero. O No, because the confidence interval does not include zero.
