A population is of size 5,500 observations.When the data are represented in a relative frequency distribution,the relative frequency of a given interval is 0.15.The frequency in this interval is equal to
A)4,675
B)800
C)675
D)825

Question

Quizplus · Accepted Answer

Using the formula for relative frequency:
relative frequency = frequency / sample size

We can rearrange the formula to solve for frequency:
frequency = relative frequency x sample size

Plugging in the values given in the problem:
frequency = 0.15 x 5,500
frequency = 825

Therefore, the frequency in the given interval is 825, so the best choice is D.
