A company manager wants to compare the satisfaction levels of his customers from two stores belonging to his company. According to his research, 249 out of 300 people are satisfied with shop A, and 348 out of 400 people are satisfied with shop B. Which of the following hypothesis states that there is a significant difference between customer satisfaction levels?

Answer A, B1, and B2: A. The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population. B. Researchers interested in lead exposure due to car exhaust sampled the blood of 52 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 124.32 µg/l and a SD of 37.74 µg/l; a previous study of individuals from a nearby suburb, with no history of exposure, found an average blood level…
In the past decade there have been concerns about the amount of mercury in fish. To investigate the proportion of contaminated fish in various regions, scientists took a sample of fish off the coast of China and off the coast of Brazil.† Assume pC represents the true population proportion of fish off the coast of China that are contaminated and pB represents the true population proportion of fish off the coast of Brazil that are contaminated. (a) Which of the following is the correct null hypothesis for this situation? μC = μB pC = pB pC ≠ pB p̂C = p̂B (b)Which of the following is the correct alternative hypothesis to test if the population proportion of contaminated fish off the coast of China is different than the population proportion of contaminated fish off the coast of Brazil? p̂C > p̂B pC > pB pC < pB pC ≠ pB
A medical device company has developed a new needle that they claim reduces the incidence of injection-site reactions for a particular medication. An experiment is to be conducted to determine if there is sufficient evidence to make that claim. Which of the following is a correct description and consequence of a Type II error? A. A Type II error would occur if the medical device company incorrectly administers the medication with the new needle, causing it to be impossible to determine whether the number of injection-site reactions have increased or decreased with the new needle. B. A Type II error would occur if, in reality, the new needle does not reduce the incidence of injection-site reactions, but the significance test detects such a difference. The consequence of such an error would be that the medical device company would produce this new needle, but it would not be beneficial. C. A Type II error would occur if, in reality, the new needle reduces the incidence of…

A major airline company is concerned that its proportion of late arrivals has substantially increased in the past month. Historical data shows that on average 18 percent of the company airplanes have arrived late. In a random sample of 1,240 airplanes, 190 airplanes have arrived late. If we are conducting a hypothesis test to determine if the proportion of late arrivals has decreased, what is the alternative hypothesis? A) Ha: p ≥ .18 B) Ha: p > .18 C) Ha: p ≤ .18 D) Ha: p < .18
