Suppose you drew a sample of 300 patients who underwent knee replacement surgery at your hospital and computed the 95% confidence interval of profit per surgery in this sample (in dollars) as [-173,-102]. This means that you are 95% confident that mean profit per surgery is larger than what value?
Homework Answers
If we have 95% confidence interval of profit per surgery in this sample (in dollars) as [-173,-102].
It means we are 95% confident that mean profit per surgery is larger than 0

Suppose a hospital would like to estimate the proportion of patients who feel that physicians who care for them always communicated effectively when discussing their medical care. A pilot sample of 40 patients found that 22 reported that their physician communicated effectively. Determine the additional number of patients that need to be sampled to construct a 99% confidence interval with a margin of error equal to 8% to estimate this proportion. the additional patients that need to be sampled is...

a) Suppose you collect a SRS of size n from a population and from the data collected you computed a 95% confidence interval for the mean of the population. Which of the following would produce a new confidence interval with larger width (larger margin of error) based on these same data? A. Use a larger confidence level. B. Use a smaller confidence level. C. Nothing can guarantee absolutely that you will get a larger interval. One can only say the...

9. Two arthroscopic surgeries were compared among patients suffering from osteoarthritis who had at least moderate knee pain. The lavage type has the joint flushed with fluid and no instrument is used to remove tissue; the debridement type has the joint flushed with fluid and an instrument is used to remove tissue. Knee pain scores, ranging from 0 to 100 with higher scores indicating severe pain, were obtained for patients randomly assigned to the two groups after the surgery and...

O-7 points BowskyintroStatt 8PR.018. My Notes Ask Your Teacher A sample of 20 heads of lettuce was selected. Assume that the population distribution of head weight is normal. The weight of each head of lettuce was then recorded. The mean weight was 2.2 pounds with a standard deviation of 0.1 pounds. The population standard deviation is known to be 0.2 pounds. Construct a 95 % confidence interval for the population mean welght of the heads of lettuce. State the confidence...

Part A: Suppose you work for a pharmaceutical company that is testing a new drug to treat ulcerative colitis. You conduct a random sample of 34 patients on the new drug and 14 of them indicated a decrease in symptoms since starting the drug regimen. You construct a 90% confidence interval for this proportion to be ( 0.2733 , 0.5502 ). What is the correct interpretation of this confidence interval? 1) We are certain that 90% of patients will be...

Suppose you monitor quality assurance for a local hospital and want to estimate the average length of stay (LOS) at your hospital. You take a random sample of 30 patients and find that the average LOS is 3.8 days with a sample standard deviation of 1.2 days. What is the 95% confidence interval for the population average length of stay? Select one: (3.43, 4.17) (3.35, 4.25) (3.20, 4.40) (3.61, 3.82) none of these are correct
