iren [92.7K]

Answer:

Hello, The answer it's D.

Step-by-step explanation:

Assume that the data for both movies and basketball games are normally distributed.

Therefore, the median and the mean are assumed equal.

The standard deviation, σ, is related to the interquartile range by

IQR = 1.35

From the data, we can say the following:

Movies:

Range = 150 - 60 = 90 (approx)

Q1 = 62 (approx), first quartile

Q3 = 120 (approx), third quartlie

Q2 (median) = 90 (approx)

IQR = Q3 - Q1 = 58

σ = IQR/1.35 = 58/1.35 = 43

Basketball:

Range = 150 - 90 = 60 approx

Q1 = 95 (approx)

Q3 = 145 (approx)

Q2 = 125 (approx)

IQR = 145 - 95 = 50

σ = 50/1.35 = 37

Test the given answers.

A. The IQRs are approximately equal, so they are not good measures of spread. This is not a good answer.

B. The std. deviation is a better measure of spread for basketball. This is not a good answer.

C. IQR is not a better measure of spread for basketball games. This is not a good answer.

D. The standard deviation is a good measure of spread for both movies and basketball. This is the best answer.

Answer: D

Leokris [45]

Answer:

78.539816 ft²

Step-by-step explanation:

To calculate a circle's area you have to multiple pi with the square of the circle's radius (the radius of a circle is half of its diameter): π·5ft²

5ft² = 5ft·5ft = 25ft

π = 3.14159...
