Q1. Industrial engineers periodically conduct "work measurement" analyses to determine the time used to produce a single unit of output. At a large processing plant, the total number of man-hours required per day to perform a certain task was recorded for 50 days. His/her information will be used in a work measurement analysis. The total man-hours required for each of the 51 days are listed below. 128 119 195 97 124 128 142 98 108 120 112 111 150 117 122 124 118. 113 109 124 97 138 133 136 120 112 146 97 116 92 122 125 131 120. 128 103 135 114 109 100 111 131 113 132 116 98 112 138 100 88 1. a) Compute the mean, the median, and the mode of the data Comment on the results. 2. b) Find the range, the variance, the standard deviation, and the mean deviation, coefficient of variation, coefficient of mean deviation, and coefficient of skewness of the data 3. c) Find the 75th percentile for the data on total daily man-hours. 4. d) Construct a stem and leaf display and box plot for the data.
