Is pokemon sun and moon offline game?

Yes and no

Step-by-step explanation:

some of it does but mostly no

the correct answer is:

a) z690 is within 1 standard deviation of the mean.

explanation:

a z-score tells us how many standard deviations away from the mean a value is.

a credit score of 690 is on the mean, so it is not away from it at all; this makes a z-score for a credit score of 690 equal to 0.

since it is not away from the mean, it is within 1 standard deviation above or below the mean.
