ASSIGNMENT 24-01-2013

Question 1:

plot(k1,res)
qqnorm(res)
qqline(res)

Comment: Since the residual plot is not scattered but shows a parabolic pattern, we can say that linearity is not applicable in this case. 

Question 2:
Using linear regression,

a) Residual value

 

b)

c) Plotting qqplot and qqline

qqnorm(res1)

Question 3:

Analysis
p value=0.687

Since p-value is greater than 5%, we cannot reject the null hypothesis
