If M represents the median and D the mode of the measurements 5, 9, 3, 5, 7, 5, 8 then (M, D) is
-
A.
(6, 5) -
B.
(5, 8) -
C.
(5, 7) -
D.
(5, 5) -
E.
(7, 5)
Correct Answer: Option D
Explanation
first re-arrange the given data in the form 3, 5, 5, 7, 8, 9 Mean(x) = (frac{sum x}{N})
= (frac{42}{7})
= 6, re-arrange thenumbers,
3, 5, 5| 7, 8, 9 median(D) = 5
(m, d) = (5, 5)
