Question

A meteorology team recorded the wind speeds (in km/h) of storms over a period of time. The frequency distribution of wind speeds is given below.

Table displaying wind speed ranges in km/h and their corresponding frequencies recorded by a meteorology team.

Using the frequency distribution above, find:

(i) The class limits of the first class

(ii) The class boundaries of the first class

(iii) The class midpoint of the first class
