24. The following are test results of 25 students (mark out of 100): 86,98,67,25,66,85,76,82,100,99,65,85,74,65,12,81,76,80,35,66,74,51,49,55,59. a. Determine the five-number-summary (i.e., median, lower and upper quartiles, and the 2 extreme values) for these 25 test results and construct the box-plot. Write down the outliers identified by the 1.5 IQR method. (Note: the outliers need not be discarded in the 5-number summary but they must be separated in the box-plot.)
