Answer:
Mean = 36.67
Median = 36.5
Mode = 38
Explanation:
Mean = [(35*8) + (37*7) + (37*4) + (38*9) + (39*2)] / (8+7+4+9+2)
Mean = (280 + 252 + 148 + 342 + 78) / 30
Mean = 1100 / 30 = 36.67
Median = Frequency of 35 and 36 is 15 total. Frequency of 37, 38, and 39 is the remainder 15 total. (36+37)/2 = 36.5
Mode = the most frequently-ocurring number = 38 (frequency of 9)
