In a study of smokers who tried to quit smoking with nicotine patch therapy, 39 were smoking one year after the treatment, and 32 were not smoking one year after the treatment (based on data from "High Dose Nicotine Patch Therapy," by Dale et al., Journal of the American Medical Association, Vol. 274, No. 17).

In a study of smokers who tried to quit smoking with nicotine patch therapy, 39 were smoking one year after the treatment, and 32 were not smoking one year after the treatment (based on data from. We want to use a 0.05 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking a year after the treatment.
In one study of smokers who tried to quit smoking with nicotine patch therapy, 39 were smoking one year after treatment and 35 were not smoking one year after the treatment. Use a 0.10 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking one year after the treatment. Do these results suggest that the nicotine patch therapy is not effective?
In a study, 28 adults with mild periodontal disease are assessed before and 6 months after implementation of a dental-education program intended to promote better oral hygiene. After 6 months, periodontal status improved in 15 patients, declined in 8, and remained the same in 5.9.1 Assess the impact of the program statistically (use a two-sided test).
In a study of 90 patients on renal dialysis, Farhad Atassi (A-7) assessed oral home care practices. He collected data from 30 subjects who were in (1) dialysis for less than 1 year, (2) dialysis for 1 to 3 years, and (3) dialysis for more than 3 years. The following table shows plaque index scores for these subjects. A higher score indicates a greater amount of plaque. At the 5% level of significance test the claim that the plaque index scores differ between these groups.

Let population 1 be drivers of age 25-34 and let population 2 be drivers of age 50-59. An insurance company collects data on seat-belt use among drivers in a country. Of 1900 drivers 25-34 years old, 19% said that they buckle up, whereas 487 of 1800 drivers 50-59 years old said that they did. At the 10% significance level, do the data suggest that there is a difference in seat-belt use between drivers 25-34 years old and those Use the two-proportions z-test to conduct the required hypothesis test. What are the hypotheses for this test?

In a winter of an epidemic ﬂu, the parents of 2000 babies were surveyed by researchers at a well-known pharmaceutical company to determine if the company’s new medicine was effective after two days. Among 120 babies who had the ﬂu and were given the medicine, 29 were cured within two days. Among 280 babies who had the ﬂu but were not given the medicine, 56 recovered within two days. Is there any signiﬁcant indication that supports the company’s claim of the effectiveness of the medicine? Use a significance level of 0.10

The research department at the home office of New Hampshire Insurance conducts on-going research on the causes of automobile accidents, the characteristics of the drivers, and so on. A random sample of 400 policies written on single persons revealed 120 had at least one accident in the previous three-year period. Similarly, a sample of 600 policies written on married persons revealed that 150 had been in at least one accident. At the .05 significance level, is there a significant difference in the proportions of single and married persons having an accident during a three year period? Determine the p-value.
