Question

the mean of the temperatures in the chart is 24° with a standard deviation of 4°. which temperature is more than one standard deviation above the mean? 16° 18° 30° 27°

Explanation:

Step1: Recall the formula for one - standard deviation above the mean

The value that is one - standard deviation above the mean is given by $\text{Mean}+\text{Standard Deviation}$.

Step2: Substitute the given values

We are given that the mean $\mu = 24^{\circ}$ and the standard deviation $\sigma=4^{\circ}$. So, $\mu+\sigma=24 + 4=28^{\circ}$. We need to find the option that is greater than $28^{\circ}$.

Answer:

C. $30^{\circ}$
