Explain.arrow_forwardThis is an Epidemiology problem. Cataracts of the eye may be difficult to diagnose in the early stages. In a study to evaluate the reliability of their diagnoses, two physicians each examined the same 1,000 eyes, without knowing the other’s diagnoses. Each physician found 100 eyes with cataracts. Does this mean that the diagnoses are reliable?

A total of 34,887 men from different study sites in the United States, Canada, and Puerto Rico were randomly selected. To be eligible to participate, the men had to take a rectal examination that showed he was not suspicious of having prostate cancer and be aged 50 years or older for black men and 55 years or older for all others. Each man was randomly assigned to receive one of four treatments: selenium, vitamin E, selenium and vitamin E together, or a placebo. The men were followed up after 8 years to see if they had developed prostate cancer or not. The main question of interest is to determine if the risk of developing prostate cancer differs by the treatment taken. The data are summarized in the table below: No Prostate Cancer Prostate Cancer Total Selenium 8,752 8,737 8,702…arrow_forward
- Arthritis is a very commonly occurring affliction. It is a major cause of lost work time and often results in serious disability. Of the many types of arthritis, the most common type is osteoarthritis. This condition is frequently due to wear and tear in the joints and is more likely to be found in people over 50. It is very painful in the weight-bearing joints, such as the knees and hips. Cartilage wears away on the bone ends, causing pain and swelling. Osteoarthritis may develop after an injury such as a bone fracture or a joint dislocation. To reduce the amount of time osteoarthritis patients are absent from work, it is important for them to have effective pain relief. An experiment was conducted to compare the effectiveness of three new analgesics: A1, A2, and A3. A clinic evaluated a large group of patients and identified 45 patients with a moderate level of pain. Fifteen of the 45 persons were then randomly assigned to one of the three analgesics. The patients were then…arrow_forwardThe term 'Boomerang Generation' refers to the recent generation of young adults who have had to move back in with their parents. In a 2012 survey, 198 out of 801 randomly selected young adults (ages 18-34) had to move back in with their parents after living alone. In a similar survey from the year 2000, 284 out of 1811 young adults had to move back in with their parents. The table below summarizes this information. The standard error (SE) is given to save calculation time. year total # who moved back (xx) total # in survey (nn) proportion p^=x/np^=x/n 2012 198 801 0.247191011235955 2000 284 1811 0.156819436775262 Standard Error: SE = 0.0164608118673214 Test the claim that a greater proportion of all young adults moved back in with their parents in 2012 than in 2000.

There are generally two types of errors that students report: random, those caused by unknown or unpredictable error in the experiment, and systematic, those that come from errors in the measuring instruments. Students sometimes mistakenly include errors in reading an instrument or errors in calculation as systematic errors. Physics professors suspect that less experienced students may report systematic lab errors differently than more experienced students do, so they sampled lab reports of n1 = 120 first-year physics students and n2 = 76 second- and third-year (combined) physics students to compare the ratios of reported systematic errors in their lab reports with the following results. 71 first-year students reported systematic lab errors in their reports. 47 second- and third-year students reported systematic lab errors in their reports.

- David Anderson has been working as a lecturer at Michigan State University for the last three years. He teaches two large sections of introductory accounting every semester. While he uses the same lecture notes in both sections, his students in the first section outperform those in the second section. He believes that students in the first section not only tend to get higher scores, they also tend to have lower variability in scores. David decides to carry out a formal test to validate his hunch regarding the difference in average scores. In a random sample of 18 students in the first section, he computes a mean and a standard deviation of 77.4 and 10.8, respectively. In the second section, a random sample of 14 students results in a mean of 74.1 and a standard deviation of 12.2. Sample 1 consists of students in the first section and Sample 2 represents students in the second section. a. Construct the null and the alternative hypotheses to test David’s hunch.…arrow_forwardWhat is the difference between single and double blinding?arrow_forwardDr. Mackintosh believes a new olfactory therapy would be more successful in promoting weight loss among obese patients. His patients are first weighed and then randomly assigned to olfactory therapy, dance therapy, or a control condition. At the end of the three weeks, the amount of weight lost is recorded. The results indicate no significant difference in the amount of weight lost between the three conditions. If differences in conditions were detected, but did not really exist, what kind of error occurred?arrow_forward
