a. .07

b. .13

c. .80

d. .87

Answer 1

Answer:

0.87

Step-by-step explanation:

Given that in a sample of 100 people, 57 completed only high school, 23 went on to complete only some college, 13 went on to complete a two-year or four-year college, and 7 went on to graduate school

Out of 100 people only 13 people went on to complete a two year or five year college.

Hence out of 100 people people who does not have a two year or four year college degree = 100-13 = 87

proportion of the sample does not have a two-year or four-year college degree=$\frac{87}{100} \\=0.87$
