Efron and Tibshirani discuss the scor(bootstrap) test score data on 88 students who took examinations in five subjects [91, Table 7.1], [194, Table 1.2.1]. The first two tests (mechanics, vectors) were closed book and the last three tests (algebra, analysis, statistics) were open book. Each row of the data frame is a set of scores (x1,...,x25) for the ith student. Obtain bootstrap estimates of the standard errors for each of the following correlation estimates: 12 = p(mec, vec), 34 = ô(alg, ana), 35 = ô(alg, sta), ô45 = ô(ana, sta).
