A statistics teacher started class one day by drawing the names of 10
students out of a hat and asked them to do as many pushups as they
could. The 10 randomly selected students averaged 15 pushups per
person with a standard deviation of 9 pushups. Suppose the
,distribution of the population of number of pushups that can be done
is approximately normal. Which of the following statements is true?
