Shown below is a contingency table showing cross classification of educational attainment and diabetic state for a random sample of 1346 people in a region (HS is high school).

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?
Geneticists examined the distribution of seed coat color in cultivated amaranth grains, Amaranthus caudatus. Crossing black-seeded and pale-seeded A. caudatus populations gave the following counts of black, brown, and pale seeds in the second generation. Seed Coat Color Seed Count black brown 342 71 pale 20 of all such seeds 3 According to genetics laws, dominant epistasis should lead to being black, brown, and pale. We want to test this theory at the 10% significance level. (a) Find the value of the test statistic. (b) Fiind the critical value. (c) What is the conclusion?

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.

The Joint Commission on Accreditation of Healthcare Organizations mandated that hospitals ban smoking by 1994. To study the effects of this ban on smoking behaviors, subjects were randomly selected from two different populations: those from hospitals with the ban and those from hospitals without the ban. Investigators were interested in determining if this smoking ban had any impact on the proportion of smokers employed at each hospital that then quit smoking. Among 843 smoking employees of hospitals with the smoking ban, 56 quit smoking during the study period. Among 703 smoking employees from workplaces without the smoking ban, 27 quit smoking during the study period. Below is the Stata output that was run to determine if there was a statistically significant difference between these two proportions at the α=0.05 level. A. What is the estimate of the proportion of smokers from the hospitals that implemented the ban that quit smoking (the blank labeled "C" in the above output)?…

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

In 2015, a survey found that 38% of Americans were supportive of online education for elementary and secondary education. With the increase in contagious viruses, it is of interest if this proportion has changed. In a 2019 poll, 51% of 1028 Americans were supportive of online education for elementary and secondary education. At the 10% significance level, do the data provide sufficient evidence to conclude that the percentage of all American adults who support online education for elementary and secondary education has changed from what was believed in 2015? Choose the choice that gives the null and alternative hypothesis.
An American medical team wishes to test whether passive smoking affects the chance of children contracting bronchitis. Historically, the disease has been known to occur at least once in 20% of children aged 12. The team analysed the results of a random sample of 250 12-year-old children who were passive smokers, and found that 30 of these had contracted bronchitis at least once in their lives. Use a 5% level of significance to test the claim that the proportion of children who are passive smokers is 20%.
