A physician employed by a large corporation believes that due to an increase in sedentary life in the past decade, middle-age men have become fatter. In 1995, the corporation measured the percentage of fat in their employees. For the middle-aged men, the scores were normally distributed, with a mean of 22%. To test her hypothesis, the physician measures the fat percentage in a random sample of 12 middle-aged men currently employed by the corporation. The fat percentages found were as follows: 24, 40, 29, 32, 33, 25, 15, 22, 18, 25, 15, 22, 18, 25, 16, 27. On the basis of these data, can we conclude that middle-aged men employed by the corporation have become fatter? Use alpha = .05 (1-tail) in making your decision. %3D
