Question

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 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.

B.

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

C.

Since the sample values are the 10 highest, they give almost no information about 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.

Explanation / Answer

The correct answer will be Option B

Reason: Since the sample size is unknown, so we don;t need the list of TV personalities contains 100 names or 1000 names

With the information about just top 10 highest paid celebrities, we can't estimate the mean. median and mode, because there can be drastic differences in the salary

Hence no assumption can be said that it will be true about the mean.median and mid-range salary

Therefore, the correct answer must be Option B
