Not even close. Lots of this sort of stuff in textbooks as well. WT...H?

For the normal distribution, the ratio of area between 0 and 1 SD from the mean to that of the area between 1 and 2 SD from the mean is about 2.51. With rounding, the figure states it as 34/14, which is about 2.43. The ratio of the actual areas seen in this plot is about 3.75 (50% larger than it should be). Not even close.
