- In a study of vehicle ownership, it has been found that 30% of U.S. households do not own a vehicle, with 46% owning 1 vehicle, and the remaining owning 2 or more vehicles. The data for a random sample of 195 households in a resort community are as follows:78 owned 0 vehicles, 103 owned 1 vehicle, and the remaining owned 2 or more vehicles.When testing (at the 10% level of significance) whether the vehicle-ownership distribution in this community differs from that of the nation as a whole what is the critical value? (please round your answer to 3 decimal places)Based on a survey of 12,344 U.S. college students and 6,729 Canadian college students, Kuo, Adlaf, Lee, Gliksman, Demers, and Wechsler (2002) report that alcohol use is more common among Canadian than U.S. students, but heavy drinking (five or more drinks in a row for males, four or more for females) is significantly higher among U.S. students than Canadian students. Is this an example of a survey research design?In a study of vehicle ownership, it has been found that 30% of U.S. households do not own a vehicle, with 50% owning 1 vehicle, and the remaining owning 2 or more vehicles. The data for a random sample of 203 households in a resort community are as follows:78 owned 0 vehicles, 105 owned 1 vehicle, and the remaining owned 2 or more vehicles. When testing (at the 5% level of significance) whether the vehicle-ownership distribution in this community differs from that of the nation as a whole what is the critical value? (please round your answer to 3 decimal places)
- In a study of vehicle ownership, it has been found that 29% of U.S. households do not own a vehicle, with 49% owning 1 vehicle, and the remaining owning 2 or more vehicles. The data for a random sample of 208 households in a resort community are as follows:70 owned 0 vehicles, 101 owned 1 vehicle, and the remaining owned 2 or more vehicles.When testing (at the 5% level of significance) whether the vehicle-ownership distribution in this community differs from that of the nation as a whole what is the test statistic?Among the four northwestern states, Washington has 51% of the total population, Oregon has 30%, Idaho has 11%, and Montana has 8%. A market researcher selects a sample of 1000 subjects, with 350 in Washington, 440 in Oregon, 140 in Idaho, and 70 in Montana. At the 0.02 significance level, test the claim that the sample of 1000 subjects has a distribution that agrees with the distribution of state populations.In order to estimate the relative abundance and geographic distribution of pheasants in Iowa, the Iowa Department of Natural Resources conducts annual road side surveys of pheasant populations. On the roads bordering five randomly selected farms in one county labeled generically as Farms A, B, C, D, and E, the survey counts were as follows: Farm # Pheasants Road miles A 3 1 B 8 1 C 9 2 D 5 1 E 11 3 One hypothesis about the geographic distribution of organisms, knowns as the spatial randomness hypothesis, asserts, as applied to the pheasant survey, that pheasants are randomly distributed throughout uniform habitat in such a way that the expected number of pheasants along any stretch of road is proportional to the length of that road. The lengths of road traveled along each farm are shown in the rightmost column of the table. Do the counts from the survey support or cast doubt on the spatial randomness hypothesis for pheasants on farmland in this country? Take a = 0.05.
- The Vice-President for Academic Affairs of SLU wished to understand the distribution of students in the academic programs in the institution for the first semester of school year 2020-2021. The numbers of students by school are the following: School Number of Students Teacher Education and Liberal Arts 2,069 Natural Sciences 2,565 Nursing 3,672 Engineering and Architecture 6,534 Accountancy, Management, Computing and Information Studies 8,381 Law 1,588 Medicine 1,418 Total Do these data contradict a claim that the distribution of students in the academic programs is uniform?Assuming the total number of students studying in the top four universities in the Philippines isapproximately 158,000.And the distribution is as follows:University of the Philippines (UP) - 40% of the total numberAteneo de Manila University (ADMU) - 23,700De La Salle University (DLSU) - 25% of the total numberUniversity of Santo Tomas - 20% of the total numberAnd only the following number of students owns a tablet computer:20% of UP students85% of ADMU students90% of DLSU students85% of UST studentsWhat is the total market penetration of tablet computers among the students of the top fouruniversities?What is the total market size of tablet computers in the top four universities?According to the National Institute on Alcohol Abuse and Alcoholism, and the National Institutes of Health, 41% of college students nationwide engage in binge drinking behavior—having five or more drinks on one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college that binge drinks is lower than the national proportion. In a commissioned study, 462 students are selected randomly from a list of all students enrolled at the college. Of these, 166 admitted to having engaged in binge drinking. The college president is more interested in testing her suspicion that the proportion of students at her college that binge drinks is lower than the national proportion of 0.41. Her staff tests the hypotheses H0: p = 0.41, Ha: p < 0.41. The P-value is: Select one: below 0.01. between 0.05 and 0.1. between 0.025 and 0.05. between 0.01 and 0.025.
- A report summarizes a survey of people in two independent random samples. One sample consisted of 700 young adults (aged 19 to 35) and the other sample consisted of 200 parents of children aged 19 to 35. The young adults were presented with a variety of situations (such as getting married or buying a house) and were asked if they thought that their parents were likely to provide financial support in that situation. The parents of young adults were presented with the same situations and asked if they would be likely to provide financial support to their child in that situation. 1. When asked about getting married, 41% of the young adults said they thought parents would provide financial support and 43% of the parents said they would provide support. Carry out a hypothesis test to determine if there is convincing evidence that the proportion of young adults who think parents would provide financial support and the proportion of parents who say they would provide support are different.…A report summarizes a survey of people in two independent random samples.

The parents of young adults were presented with the same situations and asked if they would be likely to provide financial support to their child in that situation. 1. The report stated that the proportion of young adults who thought parents would help with buying a house or apartment was 0.37. For the sample of parents, the proportion who said they would help with buying a house or an apartment was 0.27. Based on these data, can you conclude that the proportion of parents who say they would help with buying a house or an apartment is significantly less than the proportion…According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institutes of Health (NIH), 41% of college students nationwide engage in "binge-drinking" behavior: having five or more drinks on one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college who binge drink is actually lower than the national proportion. In a commissioned study, 344 students are selected randomly from a list of all students enrolled at the college. Of these, 132 admit to having engaged in binge drinking.The college president is more interested in testing her belief that the proportion of students at her college who engage in binge drinking is lower than the national proportion of 0.41. What is the P-value? (Round your answer to four decimal places.)P-value = ?
