(b) For a given 10 observations on price (X) and score (Y) the following data were
obtained
SSE = 1085.903, EX2= 469.48, X= 68, EY= 24704, EY = 464 and E
XY = 3276.8
i. Develop an estimated regression equation that can be used to predict score
given the price
ii. How good is the estimated model's prediction power?
ii.
(c) A company studied the number of lost-time accidents occurring at its Nairobi
Industrial Area, plant. Historical records show that 6% of the employees suffered
lost-time accidents last year. Management believes that a special safety program
will reduce such accidents to 5% during the current year. In addition, it estimates
that 15% of employees who had lost-time accidents last year will experience a lost
time accident during the current year. What percentage of the employees will suffer
either of the lost-time accident over the two-year period?
