ASSIGNMENT 2

In the following table are recorded data showing the test scores made by salesmen on an intelligence test and their weekly sales:-

Salesmen 1	2	3	4	5	6	7	8	9	10
Test scores 40	70	50	60	80	50	90	40	60	60
Sales (sh'000') 2.5	6.0	4.0	5.0	4.0	2.5	5.5	3.0	4.5	3.0

Calculate the regression line of sales on test scores and estimate the probable weekly sales volume if a salesman makes a score of 100. (10 marks)
