Recently there has been quite a bit of controversy about the lack of definitive knowledge about the adverse side effects associated with hormone-based birth control usage. Suppose a researcher is interested in the effects of birth control in women aged 18-25 relevant to blood pressure. The researcher assumes that women in this demographic that are taking hormone-based birth control are at risk for increased blood pressure. Assume the following table contains the summary statistics of two SRSs, one from a cohort of women taking hormone-based birth control, and one from a cohort of women birth control free. Study Arm Average Systolic Blood Pressure (mmHG) Sample Standard Deviation Sample Size Birth Control 124 6.8 246 No Birth Control 116 4.3 267 Carry out the appropriate statistical procedure to determine if there is a significant difference in the systolic blood pressure between the two groups of women. Write out your null and alternative hypotheses and interpret your results. (Use an alpha level of 0.05)

NCI Cancer Bulletin, December 2, 2008 Volume 5 / Number 24 Title of the article: After Menopause, Weight Affects Breast Cancer Rates More than Mammography Use Women who are overweight or obese after menopause face an increased risk of breast cancer, but a large prospective cohort study indicates that the frequency of mammography use and screening accuracy are not the primary explanations for higher rates of breast cancer in these women. The same is true of large, invasive breast cancer tumors and advanced stage disease; risk increases with weight, but higher rates are not explained by the frequency or accuracy of screening mammography before breast cancer was diagnosed. The study appears in the December 3 Journal of the National Cancer Institute. Dr. Karla Kerlikowske of the San Francisco Veterans Affairs Medical Center and colleagues gathered data on 287,115 postmenopausal women who were registered in the Breast Cancer Surveillance Consortium database. Reflecting a trend in the…

A case-control study is planned to investigate whether bottle-fed infants are at increased risk of death from acute respiratory infections compared breast-fed infants. The mothers of a group of cases (infants' deaths, with an underlying respiratory cause named on the death certificate) will be interviewed about the breast-feeding status of the child prior to the illness leading to death. The results will be compared to with those obtained from mothers of a group of healthy controls regarding the current breast-feeding status of their infants. It is expected that about 40% of controls will be bottle-fed, and we would like to detect a difference if bottle-feeding was associated with a two-fold increase of death (OR-2). A. How many cases and controls need to be studied to give a 90% power of achieving 5% significance level. Copy and paste/print the answer from the software. B. Repeat part (A) if the OR was three-fold increase. What do you notice about the sample size needed? Explain
Chocolate contains caffeine and an endogenous cannabinoid, as well as a chemical thatmodulates serotonin production; but is it an aphrodisiac, as the Mayans and Aztecs believed?Suppose you conduct a study which measures sex drive in a group of 20 women, after eating 8ounces of chocolate. Given that you have available data from the Kinsey Institute (IndianaUniversity) about the general sex drive for women of the same demographic as in your study, youdecide to compare your group to this population estimate.If testing hypotheses about the effects of chocolate on sex drive, it would be most appropriate tocalculate a ...1)Paired sampled t2)Z-test3)Independent-samples t-test 4)One- sample t-test
Elissa Epel, a professor of health psychology at the University of California–San Francisco, studied women in high- and low-stress situations. She found that women with higher cortisol responses to stress ate significantly more sweet food and consumed more calories on the stress day compared with those with low cortisol responses, and compared with themselves on lower stress days. Increases in negative mood in response to the stressors were also significantly related to greater food consumption. These results suggest that psychophysiological responses to stress may influence subsequent eating behavior. Over time, these alterations could impact both weight and health. You are interested in studying whether students living in the dorms or students living off campus have higher cortisol levels. You ask a sample of n₁ = 25 students living in the dorms and n₂ = 30 students living off campus to record their afternoon cortisol levels for a week. The average cortisol level for students living…
The article "Americans are 'Getting the Wrong Idea' on Alcohol and Health"† reported that observational studies in recent years that have concluded that moderate drinking is associated with a reduction in the risk of heart disease may be misleading. The article refers to a study conducted by the Centers for Disease Control and Prevention that showed that moderate drinkers, as a group, tended to be better educated, wealthier, and more active than nondrinkers. Explain why the existence of these potentially confounding variables prevents drawing the conclusion that moderate drinking is the cause of reduced risk of heart disease. (Select all that apply.) Someone who is more active is more likely to avoid healthier food. Someone who is wealthier is more likely to purchase healthier food. Someone who is more active is more likely to seek out healthier food. Someone who is educated is more likely to seek out healthier food. Someone who is educated is more likely to not be aware of what…

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…
Since this research focuses on sleep habits in college students and its effect on mental health, we have proposed the research question to be what the prevalence of college student's mental health issues are due to poor sleeping habits.Previous research has shown that anxiety and depression can be two indicators of poor sleep habits in college students (Becker et al., 2018). As mentioned before, college students are also at risk of developing poor sleep habits because, as freshmen, they transition into a more significant workload than they are accustomed to doing. They are also given more freedom with their time. So, we predict a relationship between mental health and low amounts of sleep-in students. In contrast, the alternative outcome is that there will be no mental health problems arising as students lose sleep for long periods. Since getting good sleep allows us to function better throughout our days, we will likely see the impact bad quality and quantity of sleep will have on…
