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 between 180 centimeters and 185 centimeters in height?
12.5
13.5
34
68

Second Option

Step-by-step explanation:

We know that the mean is:

and the standard deviation is:

We are looking at the percentage of students between 180 centimeters and 185 centimeters in height.

This is:

We calculate the Z-score using the formula:

For

For

Then we look at the normal table

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

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
