The society wants;
- i) the data to be presented in a frequency distribution table with classes of interval 10 for easy interpretation.
- ii) to determine the number of bags harvested of maize above which half the farmers harvested so as to establish the real effect of the fertilizers.
iii) to determine the number of farmers whose harvest is 445 bags of maize and below for re-training before the second season but they lack the information.
Task:
Help the Society to;
- a) represent the data in a frequency distribution table.
- b) determine the number of bags of maize above which half of the farmers harvested.
- c) determine the number of farmers for re-training.
