Answer:
Median = sum of the observations in class ÷ total no of observations.
Sum of observations = 5+7+14+8+12+15+17+17+5+14+7+5
= 126
Total no of observations = 12
Median = 126 ÷ 12
= 10.5
Therefore median is 10.5

Answer:
arranging orders - 5,5,5,7,7,8,12,14,14,15,17,17
No. = 12
formula =( n/2+1+n/2)/2
= 12/2+1+12/2 /2
= 7th + 6th/2
In the question 7th and 6th terms are 12 and 8 respectively
= 12+8 /2
= 20/2
= 10
so, the option (b) is correct
