The following problem needs to be sketched .

100 juniors at a school took the ACT test . The scores were distributed normally with a mean of 22 and a standard deviation of 3. Label the mean and 3 standard deviations from the mean. Be sure to put actual numbers

This should help :

 

 

The mean = 22

Three SDs  occur at 13  and 31
