The following table summarises the age groups of car drivers involved in accidents in a city for a given year.
Age ( xx years)Number of accidents
16≤x<2016 \le x < 2059
20≤x<2520 \le x < 2582
25≤x<3025 \le x < 3043
30≤x<3530 \le x < 3521
35≤x<4035 \le x < 4019
40≤x<5040 \le x < 5011
50≤x<6050 \le x < 6024
60≤x<8060 \le x < 8041
(1) Draw a cumulative frequency graph for the data. (2) Estimate the median age of the drivers involved in accidents. (3) Estimate the percentage of drivers involved in accidents who had an age of 23 or less. (4) Estimate the probability that a driver involved in an accident is aged: - 27 years or less - 27 years.
