Rivers in North Carolina contain small concentrations of mercury that can accumulate in fish overtheir lifetimes. The concentration of mercury in fish tissue can be obtained by catching fish andsending samples to a lab for analysis. A study was conducted on fish from the Waccamaw andLumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations alongeach river a group of fish were caught, weighed and measured; in addition a filet from each fish wassent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish werecaught at 15 different research stations along the Waccamaw and Lumber Rivers. Data from fishcaught at one of these stations is shown in the followinng table:lengthweight161647.048.71862285555.745.21199132044.7122543.887038.5145545.8122044.0103340.4Compute the correlation between length and weight for these fish.

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of u- 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm dass rating. Peak wave heights are usually measured from land (using binoculars) off foxed cement piers. Suppose that a reading of 36 waves showed an average wave height of x- 16.9 feet. Previous studies of severe storms indicate that - 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use a - 0.01. (a) What is the level of significance? O State the null and alternate hypotheses. O H: - 16.4 ft; H,: > 16.4 ft O Ho H 16.4 t; H,: - 16.4 m (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. O The standard…
Review the examples done in class of a cube with a side of 1cm,2cm, and 4cm and their SA/V ratios. Using data from all 5 cubes (1cm,2cm,4cm,3cm, and 30cm) create a table for the data including side length, surface area, volume, and SA/V ratio.
the soil biogeochemistry in Californian salt marshes wished to explore how two of the most common plant species, pickleweed and pacific cordgrass, affected the accumulation of nitrogen in the soil. They measured the concentration of ammonium, a molecular form of organic nitrogen, in the soil, and measured or manipulated the density of pickleweed and cordgrass. Manipulations of ½ meter square plots (20 plots per manipulation) included removing all cordgrass (cordgrass removal), removing all pickleweed (pickleweed removal), or mixed (the control - nothing removed, thus mixed plots included a mixture of natural pickleweed and cordgrass). Boxplots of ammonium concentrations in each of the three manipulation treatments. Letters indicate differences among means as determined by a Tukey posthoc test following ANOVA. (b) Overall relationship between cordgrass stem density and soil ammonium content (includes data from all plot treatments). The solid black line and the gray shading represent the…

Soil samples were collected at two areas surrounding an abandoned mine and analyzed for lead. At each area several samples were taken. The soil was extracted with acid, and the extract was analyzed using flame atomic absorption spectrometry. In Area A, Pb concentrations were 1.2, 1.0, 0.9, 1.4 mg/kg. In Area B, Pb concentrations were 0.7, 1.0, 0.5, 0.6, 0.4 mg/kg. Are these two areas significantly different from each other with Pb concentrations at 90% confidence level?
Arcata, on the northern coast of California, is a small college town with a central plaza. Figure 1 shows the streets surrounding and adjacent to the town's central plaza. As indicated by the arrows, all streets in the vicinity of the plaza are one-way.

Traffic flows north and south on G and H streets, respectively, and east and west on 8th and 9th streets, respectively. The number of cars flowing on and off the plaza during a typical 15-minute period on a Saturday morning is also shown. Find a1, 2, 23, and #4, the volume of traffic along each side of the plaza.
A router is used to cut locating notches on a printed circuit board. The vibration level at the surface of the board as it is cut is considered to be a major source of dimensional variation in the notches. Two factors are thought to influence vibration: bit size (A) and cutting speed (B). Two bit sizes (1/16 and 1/8 inch) and two speeds (40 and 90 rpm) are selected, and four boards are cut at each set of conditions shown below. The response variable is vibration measured as a resultant vector of three accelerometers (x, y, and z) on each test circuit board. (a) Analyze this experiment assuming that each one of the four replicates represent a block. (b)

The operations manager of a plant that manufactures tires wants to compare the actual inner diameters of two grades of tires, each of which is expected to be 575 millimeters. Samples of five tires from each grade were selected, and the results representing the inner diameters of the tires, ranked from smallest to largest, are shown below. Complete parts (a) through (c) below. Grade X Grade Y Q 567 573 577 581 584 570 574 577 579 583 a. For each of the two grades of tires, compute the mean, median, and standard deviation. The mean for Grade X is mm. (Type an integer or a decimal.) C
b) Given P = W²H.If errors up to 2% and 1% are possible in the measured value of W and H respectively, then find the percentage error in the calculated value of P.
