Answer 1

8 2 solution here from the given data n=8 mean = El = 779.6 = 97.45 the mean exam time is 97.45 - mediam = ntifth value = 8+15th value =usthu= 947+96.5 = 95.6 Đ the median exam time is 95.6 - Mode = most repeated value. here there is no mode. Because there is no repeated values. Mode does not exist.
