(Problems 6-10) An investigator polls a representative sample of common cold sufferers, asking them to estimate the number of hours of physical discomfort caused by their most recent cold. Their estimates approximate a normal curve with a mean of 83 hours and a standard deviation of 20 hour. 6. What percentage of sufferers estimate that their colds lasted for longer than forty-eight hours? 7. What percentage suffered for fewer than 61 hours? 8. What percentage suffered for between one and three days? 9. Inverse Normal Distribution: What is the estimated number of hours for the shortest-suffering 10 percent?
