An obesity researcher conducted a study to assess whether there was a difference in the proportion (prevalence) of individuals who are obese between males and females. The following data were
reported by the researcher.

obese obese
Gender yes no total
male 20 130 150
female 50 150 200
total 70 280 350


Construct a 95% CI for pF-pM, the difference in population proportion of obesity between females and males.

Q1. In a study of binge drinking among undergraduates at Ohio University, a researcher was interested in gender differences as related to binge drinking and to drinking-related arrests. She wanted to know two things: (a) Is there a significant relationship between gender and binge drinking (as defined by 5 or more drinks at one sitting), and (b) Is there a significant relationship between gender and drinking-related arrests? A random sample of males and females were asked about their experiences with...

Consider a study on the impact of using celebrities in television advertisements. A researcher investigated the relationship between gender of a viewer and the viewer’s brand awareness. Three hundred TV viewers were asked to identify product advertised by male celebrities. The data were summarized in the following table. Gender Male Female Totals Brand Awareness Could Identify Product 95 41 136 Could Not Identify Product 55 109 164 Totals 150 150 300 a. Is there evidence of a difference between males...

Determine whether the study is an experiment or an observational​ study, and then identify a major problem with the study. A medical researcher tested for a difference in systolic blood pressure levels between male and female students who are 12 years of age. She randomly selected four males and four females for her study. This is an ▼ observational study experiment because the researcher ▼ applies a treatment to does not attempt to modify the individuals.

A researcher randomly sampled 30 graduates of an MBA program and recorded data about their starting salaries. Of primary interest to the researcher is whether starting salaries differ based on gender. The researcher performs apooled-variance t-test of the mean salaries of the females (Population 1) and males (Population 2) in the sample. Assume α = 0.10. If the p-value = 0.1898 and a two-tail test is conducted, what is the proper interpretation for the decision of this test? A There...

Suppose we want to design a new study to assess the implications of childhood obesity on poor health outcomes in adulthood. In the study we will consider total cholesterol at age 50 and incident cardiovascular disease by age 50 as the key outcomes. We will compare normal versus overweight/obese children. Assume that the standard deviation in total cholesterol is 35. a. How many normal and overweight/obese children are required to ensure that a 95% confidence interval estimate for the difference...

:  Suppose we want to design a new study to assess the implications of childhood obesity on poor health outcomes in adulthood.  In the study we will consider total cholesterol at age 50 and incident cardiovascular disease by age 50 as the key outcomes.  We will compare normal versus overweight/obese children. Assume that the standard deviation in total cholesterol is 35. You must manually calculate all parts of this problem. a.How many normal and overweight/obese children are required to ensure that a 95%...

In a focus group, a group of people is asked whether or not they would watch a new TV show. Their answers are reported by gender in the table below. Gender No Yes Total Female 46.0% 54.0% 100% Male 54.9% 45.1% 100% Total 50.45% 50.55% 100% Based on this data, what can we conclude about the relationship between gender and interest in the show? a. There does not appear to be a relationship between those two variables as the row...
