Statistics Homework Help!?

I am a little lost as to how to solve this, since it is not confidence interval. The answer is not 0.1

A simple random sample of 400 students is taken at a large university. The average height of the sampled students is 68 inches and the SD is 2 inches. The distribution of heights in the sample follows the normal curve very closely.

Approximately 68% of the students in the sample have heights in the range 68 inches plus or minus ____________ inches.
