Excessive fertilizer and surface runoff can result in heavy phosphorus concentrations and reduced oxygen levels in lakes and ponds. This can lead to die-off of insects, fish, an increase in algae, and overall reduced health of the ecosystem. With the increase in algae, you are concerned about the amount of dissolved oxygen (DO). You measure the average DO levels in randomly sampled lakes in two different types (urban and rural) at the same time of year. Conduct a hypothesis test at 5% level of significance. Is there evidence to suggest that the average DO levels are significantly higher in lakes found in rural areas when compared to lakes in more urban areas? Use the table below. What is the p-value?

What is an experiment?
In a study conducted in the Science Department of Faculty of Science, Technology and Human Development in a University; the researcher examined the influence of the drug succinylcholine on the circulation levels of androgens in the blood. Blood samples from wild, free-ranging deer were obtained via the jugular vein immediately after an intramuscular injection of succinylcholine using darts and a capture gun. Deer were bled again approximately 30 minutes after the injection and then released. The level of androgens at time of capture and 30 minutes later, measured in nanograms per milliliter (ng/ml), for 15 deers as in Table Q1. Assuming that the populations of androgen at time of injection and 30 minutes later are normally distributed:i) Find the average and standard deviation of this studyii)Determine the critical region of this problem.iii) Test at the 0.05 level of significance whether the androgen concentrations are altered after 30 minutes of restraint.
NCI Cancer Bulletin, December 2, 2008 Volume 5 / Number 24 Title of the article: After Menopause, Weight Affects Breast Cancer Rates More than Mammography Use Women who are overweight or obese after menopause face an increased risk of breast cancer, but a large prospective cohort study indicates that the frequency of mammography use and screening accuracy are not the primary explanations for higher rates of breast cancer in these women. The same is true of large, invasive breast cancer tumors and advanced stage disease; risk increases with weight, but higher rates are not explained by the frequency or accuracy of screening mammography before breast cancer was diagnosed. The study appears in the December 3 Journal of the National Cancer Institute. Dr. Karla Kerlikowske of the San Francisco Veterans Affairs Medical Center and colleagues gathered data on 287,115 postmenopausal women who were registered in the Breast Cancer Surveillance Consortium database. Reflecting a trend in the…

2.Researchers studied selenium levels in beef raised in a low selenium region of the United States. The goal of the study was to compare selenium levels in the region-raised beef to selenium levels in cooked venison, squirrel, and beef from other regions of the United States. The data in the Excel file (se_level.xlsx or se_level.txt) are the selenium levels calculated on a dry weight basis in mg=100 g for a sample of 53 region-raised cattle 11.23 29.63 20.42 10.12 39.91 32.66 38.38 36.21 16.39 27.44 17.29 56.20 28.94 20.11 25.35 21.77 31.62 32.63 30.31 46.16 56.61 24.47 29.39 40.71 18.52 27.80 19.49 15.82 27.74 22.35 34.78 35.09 32.60 37.03 27.00 44.20 13.09 33.03 9.69 32.45 37.38 34.91 27.99 22.36 22.68 26.52 46.01 38.04 30.88 30.04 25.91 18.54 25.51 Please answer the following questions: Use these data to construct: A…
