The marital status distribution of the U.S. male population, age 15 and older, is as shown below.
Percent
31.3
56.1
2.5
divorced/separated
10.1
Suppose that a random sample of 400 U.S. young adult males, 18 to 24 years old, yielded the following frequency distribution. We are interested in
whether this age group of males fits the distribution of the U.S. adult population at the 5% level. Calculate the frequency one would expect when
surveying 400 people. Fill in the table below, rounding to two decimal places.
Frequency Expected Frequency
