By how much is the mean of 30, 56, 31, 55, 43 and 44 less than the median?
A
0.75
B
0.50
C
0.33
D
0.17
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
\(Mean = \frac{30+56+31+55+43+44}{6}\)
= \(\frac{259}{6}\) = 43.167
Median = 30,31,43,44,55,56 = \(\frac{43+44}{2}\)
=\( \frac{87}{2}\) = 43.5
Median-mean = 43.5 - 43.17 = 0.33
