The following table shows the ages of the students currently at a university, given by percentage. Ages are rounded down to the number of whole years.

a. Represent the data in a percentage cumulative frequency polygon.

b. The oldest 8% of these students qualify as ‘mature’. Use your polygon to estimate the minimum age requirement for a student to be considered mature. Give your answer to the nearest month.

c. Of the 324 students who are 18–19 years old, 54 are not expected to find employment within 3 months of finishing their course.

i. Calculate an estimate of the number of current students who are expected to find employment within 3 months of finishing their course.

ii. What assumptions must be made to justify your calculations in part c i? Are these assumptions reasonable? Do you expect your estimate to be an overestimate or an underestimate?
