Question

identify the cumulative distribution that corresponds to the given frequency distribution.
Age at death.      frequency
0.25                       4
30- 59                   16
60-89                     60
90-119                  20

Answer 1

SOLUTION:

Given that

speed number of cars

0 - 29 4

30 - 59 16

60 - 89 60

90 - 119 20

=> The cumulative frequency distribution table is :-

Speed cumulative frequency

less than 30 4 (+4)

less than 60 20 (4 + 16)

less than 90 80 (4 + 16 + 60)

less than 120 100 (4 + 16 + 60 + 20)
