Rivers in North Carolina contain small concentrations of mercury that can accumulate in fish over their lifetimes. The concentration of mercury in fish tissue can be obtained by catching fish and sending samples to a lab for analysis. A study was conducted on fish from the Waccamaw and Lumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations along each river a group of fish were caught, weighed and measured; in addition a filet from each fish was sent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish were caught at 15 different research stations along the Waccamaw and Lumber Rivers. Data from fish caught at one of these stations is shown in the followinng table: length weight 1616 47.0 48.7 1862 2855 55.7 45.2 1199 1320 44.7 1225 43.8 870 38.5 1455 45.8 1220 44.0 1033 40.4 Compute the correlation between length and weight for these fish. (Assume the correlation conditions have been satisfied and round your…

Choose the correct answer. On Day 1 of a technology conference in San Diego, 15 presenters who were setting up for their sessions in Annex C became ill with flu-like symptoms. During the course of the conference, 20 participants who attended sessions in Annex C also became ill with the same symptoms. To begin calculating the rate of this outbreak, investigators should first determine A) the size of the conference population, B) the number of cases of illness, C) the number of days the conference was held, D) the location of the conference?

6. Setup: JP was curious about the sodium content of organic cornflakes. To investigate this, twenty 300-gram boxes of organic cornflakes were obtained and the sodium content was measured. The data (in milligrams) are as follows: 131.1, 130.7, 130.9, 129.5, 129.6, 128.8, 130.7, 128.3, 128.2, 129.7, 130.1, 129.3, 128.7, 129.0, 129.4, 130.4, 129.5, 130.1, 129.8, 130.0 Task: Perform a hypothesis test using R to determine if you can support a claim that the mean sodium content of this brand of cornflakes differs from 130 milligrams? Use a = 0.08 to make your decision. R Output: Upon running your analysis in R, you obtain the following results: One Sample t-test data: corn = 0.1121 t = -1.6659, df = alternative hypothesis: true mean is not equal to 130 19, р-value 92 percent confidence interval: 129.3458 130.0342 sample estimates: mean of x 129.69 Questions: (a) State the hypotheses used in performing this test.
