Premise 1 of the induction by confirmation (in chapter 2) should begin with “The hypothesis is …” or “The hypothesis is the following.” If that premise simply states the hypothesis, then the hypothesis can be repeated in the conclusion and the argument will be valid.

On p. 141, the last line in table 5.4 should be “30 females who smoke.”
