a) Compute an estimate ρ ̂ for the correlation coefficient ρ of X1 and X2 using the data.  What was the formula you used for this calculation?
b) Compute the mean of all bootstrap means and discuss.  You may wish to look at some plots of the distributions of the bootstrap replicates.
c) Compute the bootstrap estimate for the bias using B=1000 replications.
d) Compute the bootstrap estimate for the standard error using B=1000 replications.
e) Compute the 95% Bootstrap t Confidence Interval for ρ using B=1000 bootstrap replicates.
f) Compute the 95% Bootstrap Percentile Confidence Interval for ρ using B=1000 bootstrap replicates.
g) Compute the jackknife estimate for the bias.
h) Compute the jackknife biased corrected estimate for ρ.
i) Compute the Jackknife t Confidence Interval for ρ.
j) Comment on the performance of the three confidence interval methods in parts e), f) and i).
