A study was conducted to investigate drinking problems among college students. In 1983, a group of students were asked whether they hadever driven an automobile while drinking. In 1987, after the legal drinking age was raised, a different group of college students was asked thesame question. The results are as shown in the table below. Test to compare the proportions of students witha drinking problem at 0.05 level of significance, 1987 versus 1983; and provide the chi-squared statistic value below (in 2 decimal places).YearDrove while drinkingYesNo19831,2581,35519879941,643

Consider the relationship between p-values and significance levels. a. Explain why a value of z-statistic that is significant at the 1% level in a one-sided test is always significant at the 5% level. b. Explain why the reverse is not true. If something is significant at the 5% level in a one-sided test it is not necessarily significant at the 1% level.
