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...
Lung Cancer & Smoking Case Study A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The...
you need to estimate the mean number of travel days per year for outside salespeople. The mean of a small pilot study was 150 days, with a standard deviation of 36 days. If you must estimate the population mean within 10 days, how many outside salespeople should you sample? Use the 95 percent confidence level. (Round up your answer to the next higher whole number.) Number of outside salespeople

a) Approximately 500 students take a particular college statistics course each year. As an exercise, each of the 500 students in the class is given a different random sample of the previous year's 500 final grades (in percentages) and asked to construct a 95% interval estimate of the previous year's overall average. Which of the following statements is correct? About 475 of the confidence intervals will contain the actual overall average for the previous year. It is probable that 475...

IMPORTANCE Clinical outcomes for glioblastoma remain poor. Treatment with immune checkpoint blockade has shown benefits in many cancer types. To our knowledge, data from a randomized phase 3 clinical trial evaluating a programmed death-1 (PD-1) inhibitor therapy for glioblastoma have not been reported. OBJECTIVE To determine whether single-agent PD-1 blockade with nivolumab...
