Hypothesis Tests for Population Proportions
(Using P- Value)
According to a report sponsored by the National Center for Health Statistics, 74% of American women have been married by the age of 30. Patrice, a single women of 32 who has never been married, claim that this percentage is too high. To test her claim, she surveys a simple random sample of 125 American women between the ages of 30 and 44 and finds that 9 of them were married at least once by the age of 30. Does this evidence support Patrice's claim that less than 74% of American women have been married by the age of 30? Use a 0.10 level of significance.
