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°
Answer
Explanation:
Step1: Define range for one - standard deviation
The range within one - standard deviation of the mean $\mu$ with standard deviation $\sigma$ is $\mu-\sigma\leq x\leq\mu + \sigma$. Given $\mu = 24^{\circ}$ and $\sigma=4^{\circ}$, the range is $24 - 4\leq x\leq24 + 4$, or $20^{\circ}\leq x\leq28^{\circ}$.
Answer:
$22^{\circ}$
