A producer of low-calorie protein bars wants to test if the product makes consumers eat fewer calories at lunch, so he can use this claim
A producer of low-calorie protein bars wants to test if the product makes consumers eat fewer calories at lunch, so he can use this claim to improve the image of the product and get more clients. According to his advisers, people that eat these bars as morning snacks consume on average fewer calories than people who do not eat them. To have evidence that supports this claim, the company interviewed 200 people including 115 consumers and 85 non-consumers of the protein bars. They collected information about the number of calories each person consumed at lunch. The collected data shows that the consumers of the protein bars eat on average 653 calories at lunch, and the non-consumers eat on average 650 calories at lunch. Moreover, the variance for the caloric consumption at lunch among consumers is 9923 and among non-consumers is 10575. What is the value of the test statistics for this problem?
