Answer:
Organize: 1, 9, 9, 10, 11, 13, 13, 13, 15, 71
Mean: 16.5
Median: 12
Mode: 13
Step-by-step explanation:
Mean (average): 1+9+9+10+11+13+13+13+15+71 = 165 165/10 = 16.5
10-> how many numbers
Median (middle #): 1, 9, 9, 10, <u>11, 13</u>, 13, 13, 15, 71
(11+13)/2 = 12 <---11 and 13 because there are two middle numbers, so you calculate the average of those two #s
Mode (most frequent #): 1, 9, 9, 10, 11, <em><u>13, 13, 13</u></em>, 15, 71 --->13 appears the most
