Annie is concerned over a report that "a woman over
age 40 has a better chance of being killed by a terrorist
than of getting married." A study found that the likelihood of
marriage for a never-previously-wed, 40-year-old
university-educated American woman was 2.9%. To demonstrate
that this percentage is too small, Annie uses her resources at the
Baltimore Sun to conduct a simple random sample
of 516 never-previously-wed, university-educated,
American women who were single at the beginning of
their 40 and who are now 45. Of these
women, 21 report now being married. Does this evidence
support Annie’s claim, at the 0.10 level of significance,
that the chances of getting married for this group is greater
than 2.9%?
