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.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
