Question 26

The engine capacities, c c\,c litres, of 50 cars are summarised in the table below.

Engine capacity (litres)Frequency
1.0<c≤1.41.0 < c \le 1.41.0<c≤1.49
1.4<c≤1.81.4 < c \le 1.81.4<c≤1.821
1.8<c≤2.21.8 < c \le 2.21.8<c≤2.214
2.2<c≤3.02.2 < c \le 3.02.2<c≤3.06

Use linear interpolation to estimate the median engine capacity of these cars.
