Question

A recent study of 100 employees from six departments of a major corporation found 65% to be sleep deprived. The researchers concluded that the majority of corporate employees are sleep deprived. The researcher’s conclusion is suspect because it a. assumes that corporate employees are more sleep deprived than other people
b. is based on evidence that is statistically impossible
c. fails to describe the effects the sleep deprivation has
d. relies on a sample that is too small to represent the entire corporate workforce

Answer 1

Answer:

The correct answer is:

d. relies on a sample that is too small to represent the entire corporate workforce

Explanation:

In order to achieve such a general conclusion for this study, it would be necessary to develop the research in several corporations with a huge sample in each study, so the conclusion would be based in real facts. In this special case, the sample is really small and it has only been taken from one company, therefore, it cannot be generalized to all the corporations and all the workers.
