Do firms with executive directors who network with executives at other firms perform better? This was one of the questions of interest in a study published in the Journal of Accounting Public Policy (Vol. 34, 2015). One measure of firm performance used in the study was annual return on equity (ROE), recorded as a percentage. Data collected over a 5-year period for executive directors at 147 firms yielded the following summary statistics on ROI: mean = 13.93, median = 14.86, 5th percentile = -19.64, 25th percentile = 7.59, 75th percentile = 21.32, 95th percentile = 38.42, and standard deviation = 21.65. Give a practical interpretation of each of these statistics. Then, use this information to draw a sketch of the distribution of the ROI values for the 147 firms.
