Coronary stenosis (narrowing of the artery supply to the heart muscle) is a direct cause of heart disease. A theory suggests that chronic cytomegalovirus (CMV) infection narrows coronary vessels and leads to coronary heart disease. To test this theory, 75 patients undergoing angioplasty were followed for 6 months following their procedure. The 49 patients who were seropositive for CMV experienced an average luminal diameter reduction of 1.24mm (s1 = 0.83 mm). In contrast, the 26 patients who were seronegative for CMV experienced and average luminal reduction of 0.68 (s2 = 0.69).k Test whether this mean difference in luminal reduction is significant. Show all hypothesis-testing steps. Do the data support the hypothesis that chronic CMV virus infection plays a role in coronary luminal reduction? What is the 95% confidence interval?

True or False? Researchers are assessing the effects of ambient noise level and plant location on worker productivity by a two-factor ANOVA without replication, at . The results are summarized below. By comparing the F statistic for plant location with the F critical value, we reject the null hypothesis that plant location has no effect on the worker productivity. Select one: True False

A researcher is interested in the amount of sleep an individual receives after consuming a sleeping aid (Melatonin, Valerian root, and Placebo). The researcher randomly selects individuals into either group. However, some individuals drop out of the study which results in unequal sample sizes. Locate the critical region. In doing so, determine the degrees of freedom values.
In an area where there is no radioactive fallout, 1% of newborns show genetic disorders. Genetic disorders were observed in 150 out of 10000 babies born in a year in a region with radioactive fallout as a result of atomic bomb trials.Test whether radioactive fallout increases the rate of genetic defects at α = 0.05 significance level.

For a sample of 50 low- birth-weight babies, the sample mean zinc level was 17.00 and the standard error was 0.43. For a sample of 73 normal-birth-weight babies, the sample mean zinc level was 18.16 and the standard error was 0.32. Explain why the two standard errors are not the same.
