How much time do Americans spend eating or drinking?  Suppose for a random sample of 1001 Americans age 15 or older, the mean amount of time spent eating or drinking per day is 1.22 hours with a standard deviation of 0.66 hour.   Suppose Pre-school teachers would like to use the above data in order plan meal and snack time for their 3 and 4 year old students.  Could they use the same estimates as above?  Why or Why Not?
