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 ofmarriage for a never-previously-wed, 40-year-old university-educated American woman was 2.6 % . To demonstrate that this percentage is too small, Annie uses herresources at the Baltimore Sun to conduct a simple random sample of 540 never-previously-wed, university-educated, American women who were single at the beginningof their 40s and who are now 45. of these women, 20 report now being married. Does this evidence support Annie's claim, at the 0.10 level of significance, that thechances of getting married for this group is greater than 2.6 % ?Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.囲 TablesE KeypadAnswerKeyboard Shortcuts

The NAEP music assessment scores for eighth grade students are approximately N (150, 35). Find the z-scores by standardizing the following scores: 150, 140, 100, 180, and 230. The percentile score is the proportion of students who would score LESS THAN OR EQUAL TO the score for the individual student. Compute the percentile scores for the five scores.
Aspirin prevents blood from clotting and helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug named dipyridamole would make a difference for patients who had already had a stroke.
