The ages of ten students of a group are given below. The ages have been recorded in years and months:
8-6, 9-0, 8-4, 9-3, 7-8, 8-11, 8-7, 9-2, 7-10, 8-8
(i) What is the lowest age?
(ii) What is the highest age?
(iii) Determine the range?
The ages of 10 students of a group are given below:
8-6, 9-0, 8-4, 9-3, 7-8, 8-11, 8-7, 9-2, 7-10, 8-8
(i) Lowest age is 7 years 8 months.
(ii) Highest age is 9 years 3 months.
(iii) Range = Highest age – Lowest age
= 9 years 3 months – 7 years 8 months
= 1 year 7 months
