Arecent 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 peopleb. is based on evidence that is statistically impossiblec. fails to describe the effects the sleep deprivation hasd. relies on a sample that is too small to represent the entire corporate workforce

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

Explanation:

the conclusion is suspect because a 100 employee in a single corporation is too small to represent the entire corporate workforce. Larger sample size involving more than one corporation will be more representative than using a single corporation, the study is not random.

Option A is wrong because it was never stated by the researcher that  corporate employees are more sleep deprived than other people.

Option C is wrong because the effect of sleep deprivation is out of the scope of the study.

Option B is also wrong because the evidence provided is statistically possible.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
