A group of researchers studied the effect of acid rain on wildlife and collected n = 12 samples from streams in different States.They recorded the pH (X) of the water (i.e. units above pH 7), and the BCI, a measure of biological diversity (Y). The data obtainedis summarized below.DATA:Observation123456789101112pH above 7 (X)0.650.750.890.941.121.161.291.351.481.561.731.80Units of BCI (Y)16.018.915.621.123.624.926.129.219.330.733.729.4Find the coefficient of determination between pH and BCI (round to the nearest hundredth; place your answer in the box below)

Exhibit 10-11 An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below. Under Age 18 Over Age 18 N1 = 500 n2 = 600 Number of accidents = 180 Number of accidents = 150 We are interested in determining if the accident proportions differ between the two age groups.

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.

Hookworms are parasitic nematodes that live in the intestines of a host. Hookworms do their damage (often fatally) by draining blood from the intestinal wall. The data below correlate the number of hookworms and the amount of blood lost by that number of worms. (Include units below if applicable. If necessary, use a separate sheet of paper for 6c and 7c.)

For the following description of data, identify the W's (who and what was measured and when, where, why, and how it was measured), name the variables, specify for each variable whether its use indicates it should be treated as categorical or quantitative, and for any quantitative variable identify the units in which it was measured (or note that they were not provided). After several major ocean oil spills, oil tankers werere designed to have thicker hulls. Further improvements in the structural design have decreased the likelihood of an oil spill and the amount of outflow in the event of a hull puncture. A website reports the length of cleanup time, hull thickness, and cause of puncture for 40 recent major oil spills from tankers and carriers. Question content area bottom Part 1 Who was measured? A. The website B. 40 recent oil spills C. The oil tankers D. This information is not given.
