Sleep apnea is a disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. In a cross-sectional study of 390 adults who suffer from sleep apnea, it was found that 273 had gum disease. Note: In the general population, about 17.5% of individuals have gum disease.

Cholesterol: An article in the Archives of Internal Medicine reported that in a sample of 245 men, 70 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 170 women, 62 had elevated cholesterol levels. Can you conclude that the proportion of men with elevated cholesterol levels is less than the proportion of women with elevated cholesterol levels? Let p₁ denote the proportion of men with elevated cholesterol levels and p₂ denote the proportion of women with elevated cholesterol levels. Use the a= 0.05 level of significance and the P-value method with the TI-84 Plus calculator.

An SAT prep course claims to improve the test score of students. The table below shows the scores for seven students the first two times they took the verbal SAT. Before taking the SAT for the second time, each student took a course to try to improve his or her verbal SAT scores. Do these results support the claim that the SAT prep course improves the students' verbal SAT scores? Let d = (verbal SAT scores prior to taking the prep course)-(verbal SAT scores after taking the prep course). Use a significance level of α = 0.05 for the test. Assume that the verbal SAT scores are normally distributed for the population of students both before and after taking the SAT prep course. Student 1 2 3 4 567 Score on first SAT 380 440 470 490 440 Score on second SAT 420 530 530 550 460 420 410 490 430 Step 1 of 5: State the null and alternative hypotheses for the test.
