Halcion is a sleeping pill that is relatively rapidly metabolized by the body and therefore having fewer hangover effects the next morning, compared to other sleepingpills. Opponents of Halcion argue that, because this agent is so rapidly metabolized by the body, patients do not sleep as long with this drug as with Dalmane. Data on 10insomniacs, each of whom took Dalmane on one occasion and Halcion on a second, is collected. The variable measured is number of hours of sleep:Patient12345678910Number of Hours Sleep withDalmaneHalcion4.583.975.194.883.944.096.325.877.686.933.484.005.725.087.046.955.274.965.845.13Do these data suggest that Halcion is not as effective as Dalmane with respect to number of hours of sleep? Report the p-value of your test below. Round your answer to3 decimal places (e.g. 0.XXX).

Compare the two separate scatterplots. In particular, how do the associtation compare between women with pets vs. women without pets? Does one group have more variation in systolic blood pressure than the other? If so, for which group? Does systolic blood pressure seem higher for common ages between the two groups? If so, for which group?
Laureysens, et al. (2004) studied the concentration of aluminum in wood from a number of clones of poplar growing in an area with heavy pollution. The same clone was sampled and tested once in August and again in November. The researchers believed that the concentration of aluminum would be shown to be increasing over time and hence higher in November than in August. The following table gives the aluminum concentrations for twelve of the clones. Clone 1 2 3 4 5 6 7 8 9 10 11 12 Aug. 8.1 10.0 16.5 13.6 9.5 8.3 18.3 13.3 7.9 8.1 8.9 13.4 Nov. 11.2 16.3 15.3 15.6 10.5 15.5 12.7 11.1 19.9 20.4 14.2 36.8 Diff. 3.1 6.3 1.2 2.0 1.0 7.2 5.6 2.2 12.0 12.3 5.3 23.4 The data are to be analyzed using the Wilcoxon signed rank test.

A new analytical method to detect pollutants in water is being tested. This new method of chemical analysis is important because, if adopted, it could be used to detect three different contaminates - organic pollutants, volatile solvents, and chlorinated compounds - instead of having to use a single test for each pollutant. The makers of the test claim that it can detect high levels of organic pollutants with 99.6% accuracy, volatile solvents with 99.91% accuracy, and chlorinated compounds with 89.4% accuracy. If a pollutant is not present, the test does not signal. Samples are prepared for the calibration of the test and 60% of them are contaminated with organic pollutants, 27% with volatile solvents, and 13% with traces of chlorinated compounds. A test sample is selected randomly. (a) What is the probability that the test will signal? (b) If the test signals, what is the probability that the chlorinated compounds are present? Carry out all calculations exactly, then round the final…

A wood products firm uses leftover time at the end of each week to make goods for stock. Currently, there are two products on the list of items that are produced for stock: a chopping board and a knife holder. Both items require three operations: cutting, gluing, and finishing.

A special education teacher did research on whether or not there is a relationship between the number of students in his class and the number incidents of “acting out” behaviors exhibited by the autistic students in the classroom. He collects data for a year and aggregates them by month. He obtained the statistics below, r= -.863 R2=.74 b= -1.212294 a= 131.176598 10.) How does the presence of more students affect the incidents in the class? a) as students are added the incidences increase b) as students are added the incidences decrease c) the number of students does not affect acting out d) the number of students caused more incidents How much of the variability of acting out is explained by the number of students in the class?___________
