Question

Which one of the following is true according to the graph? A) More people had 4 years of education beyond high school than 3 years. B) If the sample is truly representative, then for a group of 50 people, we can expect about 32 of them to have one year of education beyond high school. C) The graph of based on a sample of approximately 62 thousand people. D) The percent of people with years of higher education greater than those shown by any rectangular bar is equal to the percent of people with years of education less than those shown by that bar. Assume 360 days in a year. Round to the nearest hundredth of a percent when necessary A = P(1 + r/n)^nt P = A/(1 + r/n)^nt A = P_e^rt Y = (1 + r/n)^n - 1B-1

Explanation / Answer

A) The bar of people with 4 years of education beyond high school is greater than that with 3 years. So the statement is true.

B) According to the graph, number of people with 1 year of education = 24 and not 32. Therefore the statement is false.

C) Approximate number of people = Sum of the graph values on vertical axis = 24+13+12+14+3+2 = 67 thousand.

Therefore, the statement is false.

D) Clearly, the percentage of people with higher education less than the first bar is zero and the percentage of people with higher education greater than the first bar is greater than zero.

So this statement is false.

The statement that is true is A)
