As practiced by many in buying skirts or pants, they use the neckline to check if the waistline of the skirts or pants fits them. We would like to study this claim by using a random sample of neckline and waistline of 15 people. The data collected are summarized as follows: Subject 1 2 3 4 5 17 8 169 10 11 12 13 14 15 Neckline 35 34 38 45 38 33 38 42 44 33 35 31 33 35 30 (cm) Waistline(cm) 83 66 97 100 86 82 77 82 91 62 93 57 67 93 57 Construct a scatter plot for the waistline and neckline using the data presented What does the scatter plot tell you about the sign of the slope of the regression equation? (positive or negative) 1-2. Estimate the regression line of neckline and waistline. Using the model, we wish to estimate the waistline given information about the neckline. Solve for the y intercept, a and the slope, b. Round off final answers to two decimal places. a = b = 3-4. The regression equation is: Waistline'= neckline 5. Using the regression equation/model for waistline in…
Organ Donors USA Today provided information about a survey of 5100 adult Internet users. Of the respondents, 2346 said they are willing to donate organs after death. In this survey conducted for Donate Life America, 100 adults were surveyed in each state and the District of Columbia, and results were weighted to account for the different state population sizes. a. What percentage of respondents said that they are willing to donate organs after death? b. Based on the poll results, what is the probability of randomly selecting an adult who is willing to donate organs after death? c. What term is used to describe the sampling method of randomly selecting 100 adults from each state and the District of Columbia?

In an article that appears on a website,† Carlton Gunn, a public defender in Seattle, Washington, wrote about how he uses statistics in his work as an attorney. He states the following. I personally have used statistics in trying to challenge the reliability of drug testing results. Suppose the chance of a mistake in the taking and processing of a urine sample for a drug test is just 1 in 100. And your client has a "dirty" (i.e., positive) test result. Only a 1 in 100 chance that it could be wrong? Not necessarily. If the vast majority of all tests given—say 99 in 100—are truly clean, then you get one false dirty and one true dirty in every 100 tests, so that half of the dirty tests are false. Define the following events as given below. TD = event that the test result is dirty TC = event that the test result is clean D = event that the person tested is actually dirty C = event that the person tested is actually clean (a) Using the information in the quote, compute the following…
