In order to study the amount of saving and income of two populations of employees (boys and girls), two samples of twenty observations are drawn from cach population, and the data is given below. Questions: 1. Can you develop a suitable hypothesis to compare between the two populations? 2. Discuss the following question without computations: Is it possible to compare between the means of the two populations? How it can be done? 3. Assume a-0.05;0.1 and interpret your results and give your conclusions.
