Question 4 Researchers wanted to investigate if there was a relationship between timing of food intake and weight regulation. In a study that followed obese and overweight individuals through a 20-week weight loss program, investigators grouped participants into early and late eaters based on the timing of their main meal. Assume weight loss is normally distributed. A summary of the weight loss (in kgs) for each group over 20 weeks is summarized below. Group Early Eater Late Eater Sample Size Sample Mean Sample SD 27 10.1 25 7.5 6.8 6.2 a) Calculate a 98% confidence interval for H Early - H Late, the difference in mean weight loss for the two groups. b) Determine whether the weight Inss for each group is the same or not.
