mars1129 [50]

Answer:

p_1 -p_2 = 0.097-0.052 = 0.045

So then the difference between the two proportions is 0.045 and if we convert this into % we got

0.045*100= 4.5%

Step-by-step explanation:

For this case we can define the following notation:

p_1 represent the unemployment rate for high school graduates with no college degree

p_2 represent the unemployment rate for college graduates with a bachelor's degree

And for this case we need to find the difference in proportions of those unemployed between these two groups, we want to find:

p_1 -p_2

From the info given we have p_1 = \frac{9.7}{100}=0.097

p_2 = \frac{5.2}{100}=0.052

And the difference:

p_1 -p_2 = 0.097-0.052 = 0.045

So then the difference between the two proportions is 0.045 and if we convert this into % we got

0.045*100= 4.5%
