In August and September 2005, Hurricanes Katrina and Rita caused extraordinary flooding in New Orleans, Louisiana. Many homes were severely damaged or destroyed; of those that survived, many required extensive cleaning. It was thought that cleaning flood-damaged homes might present a health hazard due to the large amounts of mold present in many of the homes. An article reports that in a sample of 365 residents of Orleans Parish who had participated in the cleaning of one or more homes, 78 had experienced symptoms of wheezing, and in a sample of 179 residents who had not participated in cleaning, 23 reported wheezing symptoms (numbers read from a graph). Can you conclude that the frequency of wheezing symptoms is greater among those residents who participated in the cleaning of flood-damaged homes? Find the P-value and state a conclusion. The P-value is . Round the answer to four decimal places. We (Click to select) can cannot conclude that the frequency of wheezing…

A paper published in the Journal of Dermatology and Venereology reported that nickel allergy more likely to occur in women who report cosmetic dermatitis from using eye shadow. The researcher has taken two samples in their study from a similar population. In the first sample of 131 women with cosmetic dermatitis from using eye shadow, 12 were diagnosed with a nickel allergy. While in the second sample of 250 women with cosmetic dermatitis from using eye shadow, 25 were diagnosed with a nickel allergy. Compute a 95% confidence interval that is a closely related but simpler alternative to Wilson's Method for the first and the second samples for the proportion of women with cosmetic dermatitis from using eye shadow who have a nickel allergy. (i) (ii) Compare the two confidence intervals you compute in (i). (i) Suppose you are informed that the true proportion of women diagnosed with a nickel allergy is 0.12. Explain it refers to which group.
In a study of whether taking a garlic supplement reduces the risk of getting a cold, participants were assigned to either a garlic supplement group or to a group that did not take a garlic supplement.† Based on the study, it was concluded that the proportion of people taking a garlic supplement who get a cold is lower than the proportion of those not taking a garlic supplement who get a cold. Do you think that the study was conducted in a reasonable way? What additional information would you want in order to evaluate this study? (Select all that apply.) A) whether the patients knew which treatment they were receiving B) whether the patients were randomly assigned to the treatments C) whether the patient's last name started with A through M D) whether the patient's cold lasted more than a week E) whether the experiment was conducted on a sufficient number of patients so that the differences observed could not be attributed to chance

The epidemiological, clinical, and bacteriological aspects of shigellosis were studied in a population of hospitalized children in northern Israel. Shigellosis invades epithelial cells of the colon and causes inflammation a severe cases of diarrhea and dysentery. Below is a table that lists the frequencies of two different species of Shigella: S. sonnei and S. Flexneri between hospitalized and non-hospitalized Jews and Arabs. a) Combine hospitalized and non-hospitalized children, what is the overall prevalence of: sonnei among Jewish children: ____________________________ sonnei among Arab children: ____________________________ Flexneri among Jewish children: ____________________________ Flexneri among Arab children: ____________________________ b) Calculate a 95% confidence interval for the population difference in prevalence of S. Flexneri between hospitalized Jewish children and hospitalized Arab children. Briefly interpret the confidence interval. c) Conduct the appropriate…
