JAMB - Mathematics (1989 - No. 39)
If n is the median and m is the mode of the following set of numbers, 2.4, 2.1, 1.6, 2.6, 2.6, 3.7, 2.1, 2.6, then (n, m) is
(2.6, 2.6)
(2.5, 2.6)
(2.6, 2.5)
(2.5, 2.1)
Explicación
Arrange the numbers in order, 1.6, 2.1, 2.1| 2.4, 2.6| 2.6, 2.6, 3.7
n = median = \(\frac{2.4 + 2.6}{2}\)
= 2.5
m = mode = 2.6
∴ (n, m) = (2.5, 2.6)
n = median = \(\frac{2.4 + 2.6}{2}\)
= 2.5
m = mode = 2.6
∴ (n, m) = (2.5, 2.6)
