Question

In a clinical trial, 26 out of 881 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.6% of patients taking
competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.6% of this drug's users experience flulike symptoms as a
side effect at the a = 0.01 level of significance?
.....
Because npo (1:
|- Po) =
V 10, the sample size is
5% of the population size, and the sample
the requirements for testing the hypothesis
satisfied.
(Round to one decimal place as needed.)
What are the null and alternative hypotheses?
Ho:

(Type integers or decimals. Do not round.)
Find the test statistic, zo-
Zo =(Round to two decimal places as needed.)
Find the P-value.
P-value = (Round to three decimal places as needed.)
Choose the correct conclusion below.
O A. Since P-value < a, reject the null hypothesis and conclude that there is sufficient evidence that more than 2.6% of the users experience flulike symptoms.
B. Since P-value > a, do not reject the null hypothesis and conclude that there is not sufficient evidence that more than 2.6% of the users experience flulike
symptoms.
OC. Since P-value > a, reject the null hypothesis and conclude that there is not sufficient evidence that more than 2.6% of the users experience flulike
symptoms.
O D. Since P-value < a, do not reject the null hypothesis and conclude that there is sufficient evidence that more than 2.6% of the users experience flulike
symptoms.

A cross-sectional study of 1,900 participants looked at the association between Normal Course Load (12-15 credit hours (CH)) and Anxiety among upperclassmen college students (Junior & Senior). The study included 1,000 students with a High Course Load. This study also discovered a total of 850 cases of Anxiety. Of those with a Normal course load 12% were diagnosed with anxiety like symptoms by a school psychologist.

A recent study investigated the association between sudden cardiac death and smoking history in women from a large health system. The epidemiologist reviewed the electronic health records of women who died from sudden cardiac death (n=80) and women who died of non-cardiac causes (n=80). The investigator then reviewed these records for smoking history (smoking 1+ pack/day and smoking <1 pack/day) and identified the following results. Sudden Cardiac Death 38 42 Smoke 1+ pack/day Smoke <1 pack/day Calculate the most appropriate measure of association for these data (a)-round to the nearest tenth. Other Causes 10 70

Researchers have noted a decline in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggest that the antioxidants in foods such as blueberries may reduce and even reverse these age-related declines (Joseph et al., 1999). To examine this phenomenon, suppose that a researcher obtains a sample of n = 16 adults who are between the ages of 65 and 75. The researcher uses a standardized test to measure cognitive performance for each individual. The participants then begin a 2-month program in which they receive daily doses of a blueberry supplement. At the end of the 2-month period, the researcher again measures cognitive performance for each participant. The results show an average increase in performance of Mp = 7.4 with SS = 1215. a. Does this result support the conclusion that the antioxidant supplement has a significant effect on cognitive performance? Use a two-tailed test with a = = .05.

Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent clinical study, 82 patients with Type 2 diabetes underwent this procedure, and 65 of them experienced a recovery from diabetes.

Oishi and Schimmack (2010) report that people who move from home to home frequently as children tend to have lower than average levels of well-being as adults. To further examine this relationship, a psychologist obtains a sample of n = 12 young adults who each experienced five or more different homes before they were 16 years old. These participants were given a standardized well-being questionnaire for which the general population has an average score of = 40. The sample of well-being scores had an average of M = 37 and a variance of s2 = 10.73. a. compute cohens d
The National Cancer Institute conducted a 2-year study to determine whether cancer death rates for areas near nuclear power plants are higher than for areas without nuclear facilities. A spokesperson for the Cancer Institute said, "From the data at hand, there was no convincing evidence of any increased risk of death from any of the cancers surveyed due to living near nuclear facilities." Let p denote the proportion of the population in areas near nuclear power plants who die of cancer during a given year. The researchers at the Cancer Institute have considered the null and alternative hypotheses below: А. Họ: p = value for areas without nuclear facilities Hạ: p> value for areas without nuclear facilities According to the spokesperson's statement, what is the conclusion of the National Cancer Institute? Select one of the following: Reject Ho Fail to reject Ho Reject Ha Fail to reject Ha
