A study tracked walking habits of 1136 randomly selected adults in the United States. The study found that these 1136 adults had a mean of 5117 steps per day and a standard deviation of 3000 steps per day. Is it reasonable to conclude that mean number of steps taken in a day by American adults is more than 4500 steps? Why or why not? (sentences) TTTArial v 3 (12pt) V T
