Is the standard deviation of the sample a good estimate of the variation of salaries of tv personalities in general?

The correct answer to this would be:

“No, because the sample is not representative of the whole population.”

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

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
