This is true because the mean (M) is 32 and the standard deviation (SD) is 4. Using the empirical rule, which states that approximately 68% of data falls within one standard deviation of the mean for a normal distribution, we can expect that 68% of the data will fall between M-SD and M+SD, which is 28 and 36 respectively in this case.
