(a) Using the software of your choice, plot a histogram of the data and describe the distribution of survival times. The histogram is almost symmetric. The histogram shows a clear and pronounced left skew. The histogram is uniform. The histogram shows a clear and pronounced right skew. (b) Which numerical summary would you choose for these data, and why? Because of the skew, we should choose to summarize the data using the five-number summary combined with the mean and standard deviation. Because of the skew, we should choose to summarize the data using the five-number summary or the mean and standard deviation. Because of the skew, we should choose to summarize the data using the mean and standard deviation. Because of the skew, we should choose to summarize the data using the five-number summary.
(c) What is the five-number summary of these data? Enter the answers for the Minimum and Maximum as whole numbers and your answers for Q₁. the Median and Q3 rounded to one decimal place.) Min = Q₁: Median = (₁=
Max = How does the live-number summary reflect the skewness of the distribution? The difference between Q, and the median is relatively much larger than the other differences between successive numbers. This indicates a large spread among the low observations-that is, it shows that the data are skewed to the left. The difference between Q, and the maximum is relatively much smaller than the other differences between successive numbers. This indicates a large spread among the high observations that is, it shows that the data are skewed to the left. The difference between Q, and the median is relatively much smaller than the other differences between successive numbers. This indicates a large spread among the high observations that is, it shows that the data are skewed to the right. The difference between Q, and the maximum is relatively much larger than the other differences between successive numbers. This indicates a large spread among the high observations that is, it shows that the data are skewed to the right.
