Problem 7.12 27 women with a diagnosis of inoperable or metastatic breast cancer have been followed-up for a number of years, while under continuous treatment with a medication called trastuzumab. The time (in months) each patient remained in remission was recorded. (Remission is a decrease or disappearance of signs and symptoms of cancer.) Below is the data: 88.8 98.8 97.3 47.7 33.7 17.5 73.2 35.2 11.7 17.8 28.7 21.3 58.4 82.4 90.4 61.2 10.9 24.4 15.4 96.6 85.8 19.7 50.2 16.8 31.3 93.7 47.4 Answer the following questions using R. (a) Compute the mean, median and standard deviation of the remission time. (b) Construct the boxplot of the remission time. (c) Does the remission time appear to be normally distributed? Justify your answer using a QQ plot. (d) Compute the mean, median and standard deviation of the square root of the remission time. Is there any relationship between these values and the values found in part (a)? (e) Compute the geometric mean and geometric standard deviation of the remission time.
