Read in data set w-nat-track-rec.xlsx, (National Track Records for Women, IAAF/ATFS Track and Field Handbook for Helsinki 2005), call the data matrix X. (a) Construct Y by eliminating the first column of X and display. (b) Set R corr(Y) and display. (c) Compute det (R) and display. Does det (R) indicate anything important about R? If so, what? 1 3 (d) Solve Rx = 2 and display. 1 (e) Compute the norm Rx and display. Is the value what you expect to see? Why? (f) For 2 = , compute w= Rz and display. (g) Compute the projection of z on w and display. (h) Include your code.
