Ebook: Introduction to Probability and Statistics for Engineers and Scientists

A textbook without any answers. Formulas given without any derivations. And, at least in the 3rd edition, errors that made it past the proofreaders that shouldn't have been missed!Example 2.3e, p22, a simple calculation to find the mean:x(bar) = (9+16+15+20+30+42)/40 = 3.05What did they use to calculate this? An abacus?Figure 2.6 on p 16 is labelled "A cumulative frequency plot", when in the 2nd paragraph below it is correctly stated "A cumulative relative frequency plot of Table 2.3 is given in Figure 2.6."This is just the beginning of my class... Can't wait to find more errors...
