Mean:

78 + 31 + 47 + 51 + 16 + 58 + 60 + 10 + 30 + 40 + 46 + 63 + 65 + 10 + 93 + 22 + 13 + 47 + 64 + 93 = 937

937 : 20 = 46.85

Median:

10, 10, 13, 16, 22, 30, 31, 40, 46, 47, 47, 51, 58, 60, 63, 64, 65, 78, 93, 93

• middle of the sequence ∧∧

Mode:

Number (s) that occur the most: 10, 47, and 93

Therefore, the answer is: b. mean: 46.85 median: 47 mode: 10, 47, 93
