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
lessless
than 5%.
B.
The computed mean
is notis not
close to the actual mean because the difference between the means is
moremore
than 5%.
C.
The computed mean
isis
close to the actual mean because the difference between the means is
moremore
than 5%.
D.
The computed mean
isis

Explanation / Answer
The mean will be = (42*33+47*77+52*99+57*77+62*11)/(33+77+99+77+11)
= 15224/297
51.2593
So, option B is Correct
