1. Regression on Pearson's father-son data

a) Get the classical Pearson's father-son data by the following R commands

install.packages("UsingR"); library(UsingR); data(father.son);

Or, download the data somewhere from the web (assume it is in a file called father.son.Data which is in the working directory). load it by:

father.son<-read.table("father.son.Data", header=TRUE,sep="");

fheight<-father.son[,1];

sheight<-father.son[,2];

b) Produce a scatter plot of father's height (x axis) Vs son's height (y axis). Example R command:

plot(father.son$fheight, father.son$sheight, xlab="Father's height (in)",

ylab="Son's height (in)", pch=20);

c) Add the regression line on the scatter plot

d) Report the linear regression output (including R^2 etc)
