The measurement of the height of 600 students of a college is normally distributed with a mean of 175 centimeters and a standard deviation of 5 centimeters.
what percent of students are less than 170 centimeters in height?
15.5
0.5
16.0
2.0

Third Option

Step-by-step explanation:

We know that the mean is:

and the standard deviation is:

We look for the probability that a student measures less than 170 centimeters

This is:

We calculate the Z-score using the formula:

Then we look at the normal table

Note: You can get the same conclusion using the empirical rule
