Arrange in ascending order:-
6 7 11 13 14 15 15 19 21
median = 14
lower quartile = mean of 7 and 11 = 9
upper quatile = mean of 15 and 19 = 17
Interquartile range = 17 - 9 = 8
answer is 8
compare the divisor x-3 with x-a which will give a=3 and then use remainder theorem.
Answer: First option.
Step-by-step explanation:
