Question

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of

51.4

degrees.

Low Temperature (°F)   Frequency
40-44   2
45-49   7
50-54   10
55-59   4
60-64   3

The mean of the frequency distribution is

nothing

degrees.

​(Round to the nearest tenth as​ needed.)

Which of the following best describes the relationship between the computed mean and the actual​ mean?

A.The computed mean

is notis not

close to the actual mean because the difference between the means is

moremore

than​ 5% of the actual mean.

B.The computed mean

isis

close to the actual mean because the difference between the means is

moremore

than​ 5% of the actual mean.

C.The computed mean

isis

close to the actual mean because the difference between the means is

lessless

than​ 5% of the actual mean.

D.The computed mean

is notis not

close to the actual mean because the difference between the means is

lessless

than​ 5% of the actual mean.

Answer 1

Solution:

=> the mean of the frequency distribution is 51.8

=> option C. The computed mean is close to the actual mean because the difference between the means is less than​ 5% of the actual mean.
