A new vaccine has been developed for the treatment of a major disease. 7 patients were randomly identified and vaccinated against them and it was found that they recovered on average in 5.428 days. Since the mass variance is known to be 4 days, create a confidence interval for the average of the mass at 99% confidence level.

Dr. Diet launched a new diet. He argues that it will make patients lose more than 10 Ibs. over 5 months. A random sample of 25 students follow the diet for 5 months yielding an average weight loss of 4 pounds and a sample variance of 9 Ibs. Assume that the distribution of each individual's weight loss is normally distributed with unknown mean and variance. Construct a 95% confidence interval for the mean of the distribution of each individual's weight...

4) Dr. Jackson took a trip to a remote island that has 750 residents because she was interested in studying kidney disease within the population. She took a blood tests on all residents to determine if they had kidney disease. If 50 of the residents tested positive for kidney disease, what would be the prevalence of kidney disease? Answer:  Prevalence of kidney disease = Number of residents tested positive / Total number of residents = 50 / 750 = 0.067 Extra...

Dr. Ylvis is a biologist who specializes in the study of animal sounds. He has found that almost everyone can identify the sounds of dogs, cats, birds, mice, cows, frogs, and elephants. The sound that foxes make, however, he believes is less well known. Dr. Ylvis takes a random sample of 281 adults 18-25 and asks each person to correctly identify the sound of a fox. Out of the sample of 281, 67 of them were correct. Find the lower...

A researcher is creating a new treatment protocol for Myelodysplastic Syndrome (MDS), a form of preleukemia. Following the old treatment protocol, 32% of patients with MDS will develop leukemia within 5 years of MDS diagnosis. He believes his new treatment protocol will lead to fewer MDS patients developing leukemia. He takes a random sample of 100 individuals on his new treatment protocol. Of these 100 individuals, 27 develop leukemia within 5 years of MDS diagnosis. Create a 99% confidence interval...

A modification has been made to the production line which produces a certain electronic component. Past evidence shows that lifetimes of the components have a population standard deviation of 700 hours. It is believed that the modification will not affect the population standard deviation, but may affect the mean lifetime. The previous mean lifetime was 3250 hours. A random sample of 50 components made with the modification is taken and the sample mean lifetime for these components is found to...
