Several exercises in this chapter differ from those in the 4th edition. An “*” following the exercise number indicates that the description has changed (e.g., new values). A second exercise number in parentheses indicates that the exercise number has changed. For example, “2-16* (2-9)” means that exercise 2-16 was 2-9 in the 4th edition, and that the description also differs from the 4th edition (in this case, asking for a time series plot instead of a digidot plot). New exercises are denoted with an “?”. 2-1*. (a) x = ∑ xi n = (16.05 + 16.03 +
