A survey was conducted of male high school students to determine the proportion of male students planning to attend college or university. A survey was also conducted of female high school students to determine the proportion of female students planning to attend college or university. In the survey of male high school students, a group of 10,000 students were polled, and 71% indicated they were planning to attend college or university. In the survey of female high school students, a group of 9500 students were polled, and 75% indicated they were planning to attend college or university.
Use a calculator to construct a 90% confidence interval for the difference in population proportions p1−p2, where p1 represents the population proportion of male students who are planning to attend college or university and p2 represents the population proportion of female students who are planning to attend college or university.

A researcher is interested in determining whether there is a difference in male college students and female college students' preference for taking online classes over on-campus classes. The researcher surveys 82 female students, and found that 15 preferred online classes. The researcher surveys 70 male students, and found that 10 preferred online classes. Let's perform a hypothesis test at the 5% significance level. Test whether the proportion of females who prefer online classes is greater than the proportion of males...

Large Sample Proportion Problem. A survey was conducted on high school marijuana use. Of the 2266 high school students surveyed, 970 admitted to smoking marijuana at least once. A study done 10 years earlier estimated that 45% of the students had tried marijuana. We want to conduct a hypothesis test to see if the true proportion of high school students who tried marijuana is now less than 45%. Use alpha = .01. What is the critical value for this test?...

A study is conducted to determine what percentage of students live on campus at a large university. In a random sample found of 50 male students, it was found that that 27 of them lived on campus. In a sample of 55 female students, it was found that 40 lived on campus. At the .05 level of significance, does this sample data provide sufficient evidence to conclude that a difference exists between the proportion of male students who live on...
