Question

For one study, researchers sampled over 100,000 first-time candidates for the certified public accountant (CPA) exam and recorded the total semester hours of college credit for each candidate. The mean and median for the data set were 133.64 and 128 hours, respectively.

A.The most frequent number of semester hours a candidate reported is 128 hours.

B.Half the candidates had more than128 credit hours and half the candidates had less than 128 credit hours.

C. The sum of all the candidates' credit hours divided by the total number of candidates is equal to 128 hours.

Explanation / Answer

Solution: Option ( B )

Given,

mean = 133.64

median = 128

Mean = The arithmetic mean (or mean ) of a sample is the sum of the sampled values divided by the number of items in the sample:

Median = The median is the value separating the higher half of a data sample,or a population, from the lower half.

here only Option ( B ) is relevant to the definition of median so only

"Option ( B ) = Half the candidates had more than128 credit hours and half the candidates had less than 128 credit hours" is true
