probability in normal distribution (very basics) [on hold]
-2
Suppose X is random variable of height of males. X ~ N(175,25). (i.e., average=175, standard deviation 5).Then I can say that if take a random male, there is probability of 0.687 that the height of a person will be between 170 and 180 (i.e., one standard deviation).
Am I correct?
Thanks.

You should edit the question to indicate whether $5$ is $sigma$ or $sigma^2$. Note the usual notation is $N(mu,,sigma^2)$.

My doubts are because it is usually said not in probability terms: "About 68% of values drawn from a normal distribution are within one standard deviation σ away from the mean" (en.wikipedia.org/wiki/Normal_distribution)

John, yes, it's correct (assuming the mean is 175 and the standard deviation is 5). Between the values 170 and 180 one has approximately a probability of 0.68. However, just to avoid confusion and state things properly you should edit your question.
