IQ tests supposedly measure our intelligence. They typically are ‘normed’ so that they have a mean of 100 and a standard deviation of 15. (Higher scores show higher intelligence.) Use the graph and use the z-score and percents from columns b and c in Table A, when relevant. If you scored 132, what is your z-score? (Interpret.) Use table A  X, z(a), (b), and (c) X z (a) (b) (c)          and use the graph! Write down or save your response to use in Part 2 of this quiz. Group of answer choices -2.53 z.
