APPLIED STATISTICS 2

PLEASE USE R, SHOW R CODE AND OUTPUT, with conclusion

  1. Let x<-c(1,2,3,4,5,6,7,8), y<-c(4,6,3,7,8,3,9, 6.5). By vector operation (other method will get 0 point), find

a). the equation of regression line, that is, find a, b.

b). Find SSR, SSE

c). Find F-value

d). Find p-value

e). Make your decision, that is, answer the question, can we say y and x have linear relationship at alpha=0.05?.
