Answers & Comments
Answer:
a.
Mean: (29+34+37+22+15+38+40)/7 = 31.3
Median: Arranging the numbers in order: 15, 22, 29, 34, 37, 38, 40. Thus, the median is 34.
Mode: There is no mode as no number appears more than once.
b.
Mean: (5+6+7+7+9+9+9+10+14+16+20)/11 = 10
Median: Arranging the numbers in order: 5, 6, 7, 7, 9, 9, 9, 10, 14, 16, 20. Thus, the median is 9.
Mode: The mode is 9 as it appears the most number of times.
c.
Mean: (82+61+93+56+34+57+92+53+57)/9 = 65
Median: Arranging the numbers in order: 34, 53, 56, 57, 57, 61, 82, 92, 93. Thus, the median is 57.
Mode: There is no mode as no number appears more than once.
d.
Mean: (26+32+12+18+11+12+15+18+21)/9 = 18
Median: Arranging the numbers in order: 11, 12, 12, 15, 18, 18, 21, 26, 32. Thus, the median is 18.
Mode: The mode is 12 as it appears twice, which is more than any other number.
e.
Mean: (25+33+35+26+29+35+45+28+39+37+38+32+45+38+29+47+34+40+25+45)/20 = 35.1
Median: Arranging the numbers in order: 25, 25, 26, 28, 29, 29, 32, 33, 34, 35, 35, 37, 38, 38, 39, 40, 45, 45, 45, 47. Thus, the median is 35.
Mode: The mode is 45 as it appears three times, which is more than any other number.
