STATISTICS PLEASE HELP

A recent survey asked 874 people to identify what education they have achieved. The accompanying table summarizes the results. Does this table describe a relative frequency distribution? Why or why not?

Education Percent
No diploma 35%
GED diploma 65%
High School graduate 56%
Some college 48%
Associate degree 8%
Bachelor's degree 27%
Graduate degree 9%

a. Yes, the sum of the percentages is greater than 100 percent.
b. Yes, the sum of the percentages does not matter.
c. No, the sum of the percentages is not 100 percent.
d. No, the sum of the percentages is not 1.

Answer 1

a. Yes, the sum of the percentages is greater than 100 percent.

Answer 2

Answer: c. No, the sum of the percentages is not 100 percent.

Explanation:

One of the property of probability distribution says that the sum of all probabilities is equal to 1.

i.e. the sum of all the percent assigned to each variable is equal to 100%.

From, the given table , Sum of all percentages will be:-

35+65+56+48+8+27+9=248

Since 248% > 100%

Therefore, this table does not describe a relative frequency distribution.
