Exhibit 10-11
An insurance company selected samples of clients
under 18 years of age and over 18 and recorded the
number of accidents they had in the previous year. The
results are shown below.
Under Age 18
1=500
Over Age 18
722 = 600
Number of accidents = 180 Number of accidents = 150
We are interested in determining if the accident
proportions differ between the two age groups.
