Table 11.35
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. Calculate the frequency one would expect when surveying 400 people. Fill in Table 11.35, rounding to two decimal places.
Marital Status Frequency
Marital Status | Expected Frequency |
never married | 140 |
married | 238 |
widowed | 2 |
