The mean of the temperatures in the chart is 24° with a standard deviation of 4°. Which temperature is within one standard deviation of the mean? 18° 19° 22° 30°

The answer is C, 22

Step-by-step explanation:

I just took the test

22°

Step-by-step explanation:

If the mean is m and the standard deviation is s, then we can say that the temperatures that fall within 1 standard deviation of the mean will be:

m - s < temperatures < m + s

To we take the sum of mean and standard deviation: 24 + 4 = 28

and, the different of mean and standard deviation: 24 - 4 = 20

So, the temperature that is in between 20 and 28 is the temperature within 1 standard deviation of the mean.

This is the third answer, 22°
