Given that these are the top 10 salaries, do we know anything about the salaries of TV personalities in general?

A.

Since the sample values are the 10 highest, they give almost no information about the salaries of TV personalities in general.

B.

Since the sample values give information about one segment of the salaries of TV personalities, they give a lot of information about the salaries of TV personalities in general.

C.

Since the mean, median, and midrange are based on a small sample, no information is given on the salaries of TV personalities in general.

D.

Since the mean, median, and midrange are relatively reliable even with small samples, a lot of information is given on the salaries of TV personalities in general.

Are such top 10 lists valuable for gaining insight into the larger population?

A.

No, because the mean, median, and midrange are based on a small sample

B.

Yes, because such top 10 lists give partial information about the population

C.

No, because such top 10 lists represent an extreme subset of the population rather than the larger population

D.

Yes, because the mean, median, and midrange are relatively reliable even with small samples

Answer #1

The statistical software output for this problem is:

Hence,

a) Mean = 20.32

b) Median = 14.45

c) There is no mode.

d) Midrange = (8.6 + 38.1)/2 = 23.35

Since the sample values are the 10 highest, they give almost no information about the salaries of TV personalities in general.

No, because such top 10 lists represent an extreme subset of the population rather than the larger population
