(B) 5.2hr
(C)6.4hr
(D) 5.1hr
​

Answer 1

Answer:

Answer is option (A) 4.3hrs

Step-by-step explanation:

First arrange the data in ascending order

2.7, 3.5, 5.1, 8.3

Median for n=even number (4 participants)

Median = {(n/2)th term+(n/2+1)th term}

Median = {(4/2)th term +(4/2+1)th term}/2

Median = (2nd term+3rd term)/2

Median = (3.5+5.1)/2

Median = (8.6)/2

[Median = 4.3]
