12	5
15	7
35	19
8	5
9	6
17	15

a) Calculate the correlation coefficient between distance to office and late attendance.

b) Develop regression model y=a+bx concidering late attendeance as the dependent variable.

c)estimate the late attendance of an officer whose distance to office is 25km.( non liner regression)

d) draw a sctter diagramme

e) Based on the scatter diagram do you suggest that non linear model would fit better

Answer 1

e) from scatter plot and cor(X,Y) we can say that there is positively linear relation so we can use linear regression model.
