Chapter 11, Problem 2RE

Tooth Fillings The table below shows results from a study in which some patients were treated with fillings that contain mercury and others were treated with fillings that do not contain mercury (based on data from “Neuropsychological and Renal Effects of Dental Amalgam in Children.” By Bellinger et al., Journal of the American Medical Association, Vol. 295, No. 15). Use a 0.05 significance level to test for independence between the type of filling and the presence of any adverse health conditions. Do fillings that contain mercury appear to affect health conditions?

The table below refers to a case control study on the association between sulfones and streptomycin drugs in the treatment of leprosy. Subjects were sampled based on their clinical change to treatment and then asked whether they had a high or low degree of infiltration. The degree of infiltration measures a type of skin damage. We will use clinical change response scores {-1, 0, 1, 2, 3}. The question of interest is whether degree of infiltration is associated with clinical change. (a) Compute the sample proportions of having a high degree of infiltration for each clinical change group? What type of variable is Clinical Change? (B)Conduct a Cochran-Armitage trend test at the 5% significance level to determine whether there is an association between degree of infiltration and clinical change. (C)Now, ignore the fact that clinical change is an ordinal variable. Conduct a chi-squared test for association between degree of infiltration and clinical change at the 5% significance…
Female college student participation in athletics has increased dramatically over the past few decades.  Sports medicine providers are aware of some unique health concerns of athletic women, including disordered eating. A study compared disordered-eating symptoms and their causes for collegiate female athletes (in lean and non lean sports) and nonathletes. The sample mean of the body dissatisfaction assessment score was 13.4 (s=7.9) for 15 lean sports athletes (those sports that place value on leanness, including distance running, swimming, and gymnastics) and 7.4 (s=5.8) for the  67 non-lean athletes. Assume equal population standard deviations.  Find the standard error for comparing the means.  Construct a 95% confidence interval for the difference between the mean body dissatisfaction for  lean sport athletes and non lean sport athletes. Interpret.
Texting while driving: The accident rate for students who didn’t text while using a driving simulator was 7%. In a driver distraction study of 1,876 randomly selected students, the accident rate for students who texted while driving was higher than 7%. This difference was statistically significant at the 0.05 level. Which of the following best describes how we should interpret these results?  Because of the large size of the sample, these results are strong evidence that texting accounts for a much larger proportion of accidents in the population of student drivers.  With a large sample, statistically significant results suggest a large increase in the accident rate for the texting group over the control group.  With a large sample, statistically significant results may actually be only a small improvement over the control group (depending on the size of the increase in percentages).  Regardless of the sample size, a statistically significant result means there is a meaningful…
