Triglycerides are a form of fat found in the body. A recent study looked at whether men have higher triglyceride levels than women. After the data was collected, Minitab was used to find a 95% confidence interval for the difference between the mean triglyceride levels for men and women. Female: N=50, mean=86.9, SD=53.9, SE mean 7.6. Men: N=48, mean=138.4, SD=76.2, SE mean=11.0. Estmate for difference= -51.5. 95% confidence interval for difference (-78.1,-24.9). Report and interpret the 95% confidence interval in mean triglycerides beetween men and women. Fill in the blanks: Because the interval ____contain zero, the possibility that the mean difference in the population is 0 ____ be ruled out. Since the difference _____ the men\'s mean triglyceride level is _____ the women\'s mean triglyceride level.

Report and interpret the 95% confidence interval in mean triglycerides beetween men and women. Fill in the blanks: Because the interval _did not___contain zero, the possibility that the mean difference in the population is 0 _can___ be ruled out. Since the difference __is negative__ the men\'s mean triglyceride level is __greater than___ the women\'s mean triglyceride level.
