These box plots show daily low temperatures for a sample of days in two different towns.

A. The interquartile range (IQR) for town A is 20 and it is greater than town B which has IQR = 10.

Step-by-step explanation:

Interquartile range measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile.

Also, the end points of box plot shows the First and Third Quartile.

Thus Town A has First Quartile = 20

Third Quartile = 40

⇒ IQR = 40 - 20 = 20

and, Town B has First Quartile = 35

Third Quartile = 45

⇒ IQR = 45 - 35 = 10

Also, Standard deviation can't be calculate using Box- Plot.

Thus, Option A is the only correct option.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
