Before surgical removal of a diseased parathyroid gland, two tests are often performed: the standard intact test and the turbo test.Both tests measure parathyroid hormone (PTH, in ng/l), but the turbo test is very expensive. Researchers obtained data from bothtests in a sample of 48 patients to predict turbo test results (y) from standard intact test results (x). The data ranged from roughlyO to 500 ng/l, and a scatterplot showed a clear linear relationship. The published findings given are summarized exactly:y = 1.08x-4.36(r = 0.97; n = 48)What is the slope of the regression line?48-4.361.080.97

The regression line is y=1.08x-4.36.The general regression equation is y=ax+b. Here, a denotes slope and b denotes slope. In this case, the intercept is -4.36 and the slope is 1.08. Thus, the slope of the regression line is 1.08.

Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma. Over a period of months, and adult male patient has taken 13 blood test for uric acid. The main concentration was X=5.41 mg/dl. The distribution of uric acid and healthy adult meals can be assumed to be normal, with o=1.81 mg/dl. find a 95% confidence interval for the population mean concentration of uric acid in the patient's blood. What is the margin of error? (Round your answers to two decimal places.) lower limit= upper limit=

Cell Phone Radiation Listed below are the measured radiation absorption rates (in W/kg) corresponding to these cell phones: iPhone 5S, BlackBerry Z30, Sanyo Vero, Optimus V, Droid Razr, Nokia N97, Samsung Vibrant, Sony Z750a, Kyocera Kona, LG G2, and Virgin Mobile Supreme. The data are from the Federal Communications Commission (FCC). The media often report about the dangers of cell phone radiation as a cause of cancer. The FCC has a standard that a cell phone absorption rate must be 1.6 W/kg or less. If you are planning to purchase a cell phone, are any of the measures of center the most important statistic? Is there another statistic that is most relevant? If so, which one?
Ophthalmology Retinitis pigmentosa (RP) is a hereditary ocular disease in which patches of pigment appear on the retina, potentially resulting in substantial vision loss and in some cases complete blindness. An important issue is how fast the subjects decline. Visual field is an important measure of area of vision, which is measured in degree2. A visual field area for a normal person is around 11,000 degree2. The longitudinal data in Table 11.29 were provided by an individual patient. tablE 11.29 Longitudinal visual field data for one RP patient Time Visual field area ln Visit (yr) (degree2) (visual field area) 1 0 3059 8.03 2 1 3053 8.02 3 2 1418 7.26 4 3 1692 7.43 5 4 1978 7.59 6 5 1567 7.36 7 6 1919 7.56 8 7 1998 7.60 9 11 1648 7.41 10 13 1721 7.45 11 15 1264 7.14 mean 6.09 1938 7.532 sd 4.97 597 0.280 Suppose the rate of change of ln (visual field) is a linear function of follow-up time. 11.103 Write down a linear regression model that summarizes…

Sulfur compounds cause “off-odors” in wine, so winemakers want to know the odor threshold, the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25 micrograms per liter of wine (μg/l). The untrained noses of consumers may be less sensitive, however. Here are the DMS odor thresholds for 10 untrained students: 31 31 43 36 23 34 32 30 20 24 Give a 95% confidence interval for the mean DMS odor threshold among all students. Is there evidence that the mean threshold for untrained tasters is greater than 25 μg/l? State the hypotheses. Is there evidence that the mean threshold for untrained tasters is greater than 25 μg/l? What is the test statistic?
A study published by Babcock and Marks (2010) showed that the average full-time U.S. college student studied for μ = 14 hours per week (SD = 4.8 hours per week) in 2005. We want to know if this average has changed in the past 15 years. In other words, we are going to do a study in which we try to determine whether there has been an impact of the passage of time on the amount of time college students spend studying. We selected a sample of n = 64 of today’s college students and find that they spent an average of M = 12.5 hours per week studying. Does this sample indicate a significant change in the number of hours spent studying? Use a two-tailed test (this means non-directional hypothesis) with α = .05.
Patients with rheumatoid arthritis are at a greater risk of developing osteoporosis. The reasons are not well understood due to the difficulty in qualitatively assessing bone metabolism and mineral content. A researcher measures human calcitonin (HCT) levels in men with rheumatoid arthritis. The researcher randomly selects 43 men with rheumatoid arthritis and measured the mean HCT level of 33.8 pg/mL. Assume that HCT for individuals with rheumatoid arthritis follows a normal distribution with standard deviation σ = 23.6 pg/mL. 5. What is the effect on the interval width if we decreased or increase the confidence level to 90% or 99% respectively? (Hint, create the intervals)
A medical social worker is interested in examining the relationship between patients who receive social support by family members (yes/no) and the patients’ outcome (failure/success). She collected data over a period of a month (N=100). A chi square analysis revealed the following: χ2= 5.65, df = ?, p = .01. 3. Is the relationship between social support and patients’ outcome statistically significant (use the traditional rejection level)? How do you know?
