Medical tests were conducted to learn about drug-resistant tuberculosis. Of 142 cases tested in New Jersey, 9 were found to be drug-resistant. Of 268 cases tested in Texas, 5 were found to be drug-resistant. Do these data suggest a statistically significant difference between the proportions of drug-resistant cases in the two states? Use a .02 level of significance. What is the -value, and what is your conclusion?

Benson Manufacturing is considering ordering electronic components from three different suppliers. The suppliers may differ in terms of quality in that the proportion or percentage of defective
components may differ among the suppliers. To evaluate the proportion of defective components for the suppliers, Benson has requested a sample shipment of 500 components from each
supplier. The number of defective components and the number of good components found in each shipment are as follows.
Supplier
Component
Defective
17 22 42
Good
483 478 458
(a) Formulate the hypotheses that can be used to test for equal proportions of defective components provided by the three suppliers.
OH PA PB = Pc
0
H: All population proportions are not equal.
OH PA = P₁ = Pc
H: Not all population proportions are equal.
OH: All population proportions are not equal.
H₂PAP=Pc
OH,: Not all population proportions are equal.
H₂: PA=PB = Pc
(b) Using a 0.05 level of significance, conduct the hypothesis test.

- Researchers conducted a prospective cohort study to assess the association between dietary supplements and cognitive ability among children. A total of 500 children age 12-17 years who take an omega-3 fatty acid supplement are compared with 500 children age 12-17 years who do not take an omega-3 fatty acid supplement. Researchers follow the children for 2 years. During this time, 300 children who take the supplement earn what is classified as a “high” score on a cognitive test while 200 children who do not take the supplement earn what is classified as a “high” score on the same cognitive test.

Some years ago, a new brand of toothpaste was introduced in the United States. According to its advertisements, studies showed that it had "considerable success" in improving the health of a person's teeth. Suppose that these studies were designed in the following way. The manufacturer of this toothpaste chose three samples of seven people; the first sample agreed to use the new brand, the second sample used Brand A, and the third sample used Brand B. After six months, a dentist examined each person's teeth and scored the health of his or her teeth on a scale of 0 (lowest possible score) to 100 (highest possible score). The results were as follows: New Brand Brand A Brand B 65 58 54 71 60 38 53 63 43 55 90 61 34 95 94 82 89 96 77 62 82 The manufacturer of the new toothpaste says that the average score for the new brand is 2 points higher than for Brand A and 4 points higher than for Brand B.
