A new study of 170 lung cancer patients found that 123 of them died within a year, while undergoing a new treatment. Based on this sample data, compute 88% confidence limits to complete the statement below. Use Normal distribution instead of t: E=zα2.(pqn)−−−−−√ Give values as percentages, rounded to two digits after the decimal point. Do not include the % symbol in your answer.

Given a covariate Z, suppose that the log survival time Y follows a linear model with a logistic error distribution, that is, Y = ln(X) = μ + βΖ + σ W where the pdf of W is given by eu f(w) = (1 + ewy, (a) For an individual with covariate Z, find the conditional survival function of the survival time X, given Z, namely, S(x |Z). (b) The odds that an individual will die prior to time x...

Question: A pharmaceutical company has developed a new cancer treatment for pancreatic cancer, one of the most deadly diagnoses. The current 5 year survival rate for stage I pancreatic cancer is 15% with a population standard deviation of 2%, and the average 5 year survival of a SRS of 82 patients enrolled in a study sponsored by the company was 19%. A) Using α=.01, answer the question as to whether or not the new treatment is successful at increasing 5...

Suppose that, using standard treatments, 60% of patients completely recover from a disease. A new treatment is used on a random sample of 800 individuals, and 513 completely recover. Is this evidence, at the 5% level of significance, that this new treatment can improve the recovery rate? Do a complete hypothesis test, and show all work. (included the formula)

Fifty patients with leukemia received a bone marrow transplant with marrow from a sibling. Some of these patients died or relapsed and some were alive without relapse at the end of the study Interest is in the probabilty of being alive without relapse after a year. In particular, interest is in whether there is significant evidence that this probability is less than the corresponding probability for individuals who had their own bone marrow reinfused. Past data indicates that the latter...

Problem: Proportion of "Cured” Cancer Patients: How Does Canada Compare with Europe? Lung cancer remains the leading cause of cancer death for both Canadian men and women, responsible for the most potential years of life lost to cancer. Lung cancer alone accounts for 28% of all cancer deaths in Canada (32%. in Quebec). Most forms of lung cancer start insidiously and produce no apparent symptoms until they are too far advanced. Consequently, the chances of being cured of lung cancer...
