Below is a sample of 25 days(Monday through Thursday) from last year showing the restaurant income and numberof rooms occupied.
The 5-year survival rates by stage of disease, age at diagnosis, and race are provided in Table 10.24. Test whether the 5-year survival rate for breast cancer is significantly different between African American and Caucasian women who are younger than 50 years of age and have localized disease. Provide a p-value (two-tailed).
Recently, the Shine research clinic published a report stating that the regular application of a very popular sunscreen lotion NoHelios might cause some forms of skin cancer. The manufacturer of NoHelios issued an energetic counterstatement asserting that the Shine clinic's conclusions were statistically inconsistent. Wellbeing pharmacy chain has been selling NoHelios lotion for a long time. The market research department of Wellbeing wants to see what is currently happening with NoHelios lotion demand. The members of a random sample of customers were asked about their willingness to use NoHelios before and after the publication of Shine clinic's report. The answers were provided in form of a score from 0 to 10 (higher score means more willingness). Results for five customers are shown in the following table. The "before" score is matched to the "after" score, and the difference should be calculated. Suppose that it is known that such differences have approximately bell-shaped…
An experiment to determine if a migraine medication decreases a person's average number of monthly migraines is performed on 400 people who report they have several migraines a month. Researchers randomly assigned 200 people to the treatment group and 200 people to the control group. After the study, the researchers determined that 48 of the subjects in the treatment group and 28 of the subjects in the control group average fewer migraines per month. The data from the two groups are resampled 150 times, and the table shows the distribution of the differences of the proportions for the reconfigured treatment and control groups.
HIV/AIDS patients are regularly monitored for their CD4 counts in order to make sure that antiretroviral therapies are effectiveSuppose the distribution of CD4 counts in a population is approximately normal with mu = 237 and sigma = 43 . HIV patients are defined as moving into the AIDS stage of their disease course after their CD4 counts are less than 200. What proportion of patients in this population is suffering from AIDS?
A 1980 study investigated the relationship between the use of OCs and the development of endometrial cancer. The researchers found that of 117 endometrial-cancer patients, 6 had used the OC Oracon at some time in their lives, whereas 8 of the 395 controls had used this agent. Test for an association between the use of Oracon and the incidence of endometrial cancer, using a two-tailed test.
In a May 2011 study, Federal University Hospital in São Paulo, Brazil, 71 healthy pregnant women were separated into a control group and an experimental group. Those in the experimental group engaged in aerobic water exercise throughout their pregnancy whereas those women in the control group did not. After giving birth the neonatal outcome of the children of all women in the study was recorded where a negative neonatal outcome was defined as a hospital stay of more than four days. A set of similar results is shown in the table Group Positive Neonatal Outcome Negative Neonatal Outcome Water Exercise 15 15 Control Group 12 18 A hypothesis test was carried out, yielding a p-value of 0.396.

In a May 2011 study, Federal University Hospital in São Paulo, Brazil, 92 healthy pregnant women were separated into a control group and an experimental group.

The number of Muslims continues to grow throughout the world, and they are currently thesecond-largest religious group in the world. Knowing that this group has been the target of falsebeliefs about their religion, a researcher is interested in whether people who have moreinteractions with Muslim people are less likely to believe negative statements about Islam. To dothis, they surveyed a large sample of participants across Western Europe and asked themquestions about how frequently they interact with Muslim people as well as how much theyagreed with negative statements about Islam. What statistical test should be used to determine ifthere if how frequently survey participants interact with Muslim people predicts how likely theyare to agree with a negative statement about Islam? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B.
A sociologist wants to investigate the question, "Is there a relationship between texting during class and grade-point-average (GPA) among high school seniors in a large district?" Which study design is most appropriate? Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester, obtain each student’s GPA from the appropriate admissions and records office. Compare the GPA of students who routinely text during class to the GPA of students who do not text during class. Before the semester starts, randomly select 40 seniors from each high school who do not text during class. Assign 20 to the texting treatment group (text three or more times during every class meeting) and 20 to the control group (no texting during class). At the end of the semester,…
Noting the paucity of information on the effect of estrogen on platelet membrane fatty acid composition, Ranganath et al. (A-48) conducted a study to examine the possibility that changes may be present in postmenopausal women and that these may be reversible with estrogen treatment. The 31 women recruited for the study had not menstruated for at least 3 months or had symptoms of the menopause. No woman was on any form of hormone replacement therapy (HRT) at the time she was recruited. Table 5 shows the platelet membrane linoleic acid values before and after a period of HRT. What is the t critical value? 4 decimal places
