Normally+distrbuted+data+problems

The heights of 750 students at a local school were recorded and found to be approximated by the normal curve below. Which answer could represent the mean and standard deviation for these data? A.) 162, 20 B.) 162, 10 C.) 172, 11 D.) 132, 10

If you payed attention in math when we were doing normal curves you wil know that the middle number is the mean, and that the standard deviation is the space between the the numbers. So the answer is B (162, 10).
