Never Married People The percentage of males 18 years and older who have never married is 30.4. For females the percentage is 23.6. Looking at the records in a particular populous county, a random sample of 250 men showed that 84 had never married and 60 of 200 women had never married. At the 0.01 level of significance, is the proportion of men greater than the proportion of women? Use the P-value method and let p, be the proportion of men.
