Q08 An SRS of 20 orangutans is selected, and 65 cc of blood is to be drawn from each orangutan using a 100 cc syringe. In the sample, the mean volume is 64 cc and the standard deviation is 12 cc. Assume that in the population of all such procedures, the amount of blood drawn follows a Normal distribution with mean inline style mu. We are interested in a 95% confidence interval for the population mean volume. The margin of error associated with the confidence interval is Select one: a. 5.26. b. 4.64. c. 6.84. d. 2.68.

Question 16 2 pts The population mean for a standardized test is 250. A research study with N = 30 adults from Virginia had a mean score of 260, with a 95% confidence interval of the mean reported as [248, 272]. What decision should be made based on this confidence interval? o Run the hypothesis test again o Accept the research hypothesis o Reject the null hypothesis o Fail to reject the null hypothesis Question...

23. Suppose a sample of n = 50 items is drawn from a population of manufactured products and the weight, X, of each item is recorded. Prior experience has shown that the weight has a probability distribution with 6 ounces and ơ-2.5 ounces. Which of the following is true about the sampling distribution of the sample mean if a sample of size 15 is selected? a) The mean of the sampling distribution is 6 ounces b) The standard deviation of...

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...

Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
