Approximately 238 pages fall within the second standard deviation of the mean. The 68-95-99.7 rule gives that in a normal distribution, about 68% of the data fall within the first standard deviation, and 350*0.68=238. 350*0.95=332, so about 332 pages fall within the second standard deviation, and 350*99=348.95 pages fall within the third standard deviation.

$z = \pm15i \\ \Leftrightarrow {z}^{2} = {(\pm15i)}^{2} = - 225 \\ \Leftrightarrow {z}^{2} + 225 = 0$
