Answer 1

Answer:

54, 57, 64, 72, 75, 77, 78, 79, 80, 80, 84, 92

A) The range of the data is 36

Range = 92-54= 38

So, (A) is incorrect

B) Median of the data is 77

Median = n/2 th term (if even & n = 12)

= 12/2 th term

= 6th term = 77

So, (B) is the correct option.

(C) The mode of the dat is 84

80 is the mode

So, (C) is incorrect
