An increase in walking has been shown to contribute to a healthier lifestyle. A sedentary American takes an average of 5000 steps per day (and 65% of Americans are overweight). A group of health-conscious employees of a large health care system volunteered to wear pedometers for a month to record their steps. It was found that a random sample of 40 walkers took an average of 5430 steps per day, and the population standard deviation is 600 steps. At a = 0.05 can it be concluded that they walked more than the mean number of 5000 steps per day?
