(c) (4 points) Write down the R code to carry out that test. Youfirst need to store the data into a matrix.
(d) Calculate the test statistic by yourself.
(e) Write down the R code to obtain the p-value based on youranswer in
part(d).
(f) Suppose the p-value is 0.0001, what would be your really worldconclusion? (You may use Î± = 0:05.)
