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°

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.

27 is the standard value.

A quantity is expressed by how much the member of the group differs from the mean value.

Given

Mean () = 24

Standard deviation () = 4

Lowered bound =

Lowered bound = 24 - 4

Lowered bound = 20

Upper bound =

Upper bound = 24 + 4

Upper bound = 28

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

Thus, 27 lies between (20, 28).

Hence, 27 is the standard value.
