<p>^^ It’s C. Do invNorm(.67) to find the value of the z-score (or look it up in the table). You get a z score of about .44. Multiply by .3 to get .132; this is .132 inches above the mean (note: do not actually round until the very last step).</p>
<p>Also, if you couldn’t do that, you had better start studying, no offense just saying.</p>
