SUMMARY
The discussion focuses on estimating the mean weight gain of 18 respondents who quit smoking, using statistical methods. The data provided indicates weight gains of 14, 13, 20, 22, 12, 12, 17, 10, 12, 9, 11, 17, 15, 24, 29, 13, 13, and 19 pounds. With a standard deviation of 9 pounds, the mean weight gain can be calculated, and a 95% confidence interval can be established. This analysis is essential for understanding the impact of smoking cessation on weight changes.
