Among the literature on quitting smoking are data detailing the relative successfulness of people of different ages in quitting smoking. A study of 400
adults who began various smoking-cessation programs produced the data in the table below. In the table, each participant is classified according to two
variables: length of their smoking cessation period ("Less than two weeks", "Between two weeks and one year", or "At least one year") and age ("21-34",
or "35 and over"). In the table, "less than two weeks" means that the individual returned to smoking within two weeks of beginning the program;
"between two weeks and one year" means that the individual lasted the first two weeks without smoking but retuned to smoking within a year; and "at
least one year" means that the individual has not smoked for at least a year since beginning the program.
The table is a contingency table whose cells contain the respective observed frequencies of classifications of the 400 smokers. In addition, three…
2. Does the herb Echinacea help the common cold? A study investigated the impact of
echinacea vs. a standard cold medication on cold symptoms. Each subject in the study
chose to take either the echinacea or a standard cold medication in capsule fom After
taking the capsule for one week, the subjects then reported to the researchers the status of
their cold symptoms. The researchers subsequently reported that there was no
statistically significant difference in the duration of the cold between these groups.
Identify the type of study.
a) Cluster sample
b) Social acceptability bias
c) Experiment
d) Observational study

The study, sponsored by the National Cancer Institute, took 5 years and involved more than 1500 women with breast cancer and 2000 women without breast cancer; it revealed a trend between height and breast cancer: “. . . taller women have a 50 to 80 percent greater risk of getting breast cancer than women who are closer to 5 feet tall.” Christine Swanson, a nutritionist who was involved with the study, added, “. . . height may be associated with the culprit, . . . but no one really knows” the exact relationship between height and the risk of breast cancer. a.

- Captivity can influence immunological responses in some mammals. Seeber et al. (2020) investigated various aspects of immunological responses in captive and free-ranging zebras. One aspect of the study involved samples of 12 free-ranging zebras from Namibia, 9 from Tanzania, and 38 captive zebras from various zoos in Europe. (All of these were non-lactating females.) One of the measured variables from blood samples was lysozyme concentration (μg/L). (Lysozyme is a biomarker of the immune response.) The researchers were interested in investigating possible differences in lysozyme concentration between zebras in the various locations. As part of the analysis, they carried out a one-way ANOVA on the lysozyme concentrations for the zebras from the 3 locations, and found the following output.

Background The covid-19 pandemic has led to higher unemployment rates in the United States than normal because many people were laid off jobs in response to the pandemic (Al-Fadly, 2020). It is important to analyze how such as sharp increase in unemployment affected inflation in relation to how unemployment have traditionally affected inflation. The overall relationship between unemployment and inflation has traditionally been an inverse one. It is argued that when unemployment rates are higher, the number of individuals who are looking for jobs usually becomes higher than the number of job positions that are available (Putnam & Azzarello, 2015). In such a situation, employers tend to pay lower wages because there is abundance of workers which naturally leads to a lower wage inflation. This study will examine the relationship between unemployment rates and inflation rate during…arrow_forwardA cohort study is conducted to assess the association between clinical characteristics and the risk of stroke.

Four life-sized dummies of male lions provided a tool for testing female response to the unfamiliar lions whose manes varied by length (long or short) and color (blonde or dark).

What might be the effect of early exposure to antibiotics on children's development? One study followed 11,532 full-term babies all born in the county of Avon, United Kingdom, during 1991 and 1992. Exposures to antibiotics during infancy were recorded, along with measures of body mass at regular intervals over several years. The researchers found that antibiotic exposure during the first six months of life was associated with increased body mass later in childhood.arrow_forwardFoot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. The article "An Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation" (Kimberly Anderson, M.S.
