A study is being conducted to compare the intake of calories at lunch for consumers of high-fiber breakfast cereals and non-consumers of high fiber breakfast cereals. From a random sample of 43 consumers of high fiber cereals, average calorie intake at lunch was 604.02, with a population standard deviation of 64.05 calories. In a random sample of 107 non-consumers of high fiber breakfast cereals, the average calorie intake at lunch was 633.23, with a population standard deviation of 103.3 calories. Assume that training time for each group is normally distributed. Use the following notations:
μ1: The mean calorie intake at lunch for consumers of high fiber breakfast cereal
μ2: The mean calorie intake at lunch for non-consumers of high fiber breakfast cereal
The goal of the statistical analysis is to determine whether the sample data support the hypothesis that average calorie intake at lunch for consumers of high fiber breakfast cereal is lower than that for non-consumers of high fiber breakfast cereal.
