In an attempt to determine how many consultants are needed to answer questions of users at a computer center, these data are collected on X, the time in minutes required to answer a telephone inquiry: What is E[W]? Based on the signed-rank test, can we conclude that the median time required is less than 5 minutes? Explain, based on the P value of your test. (A zero score should be given the lowest rank and should be assigned the algebraic sign least conducive to rejecting the null hypothesis.)
