Question

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? 16° 18° 27° 29°

Answer 1

For whatever reason edge. nuity or e.2020 asked me this question twice on one quiz, just with different answer choices. The first choices were...

A. 18 degrees

B. 19 degrees

C. 22 degrees

D. 30 degrees

The second choices were...

A. 16 degrees

B. 18 degrees

C. 27 degrees

D. 29 degrees

THE ANSWER TO BOTH ARE C. 22 degrees & C.27 degrees

made 100% on the quiz by the way

Answer 2

Given: Mean temperature μ = 24 , standard deviation σ =4

The lower and upper bound for temperature within one standard deviation of the mean is given by,

Lower bound = μ - σ = 24 - 4

Lower bound = 20

Upper bound = μ + σ = 24+ 4

Upper bound = 28

The temperature value between (20, 28) is said to be within one standard deviation of the mean.

From given option 27° lies in between (20°, 28°), hence 27° is the temperature value that is within one standard deviation of mean.
