A value of 26 is how many standard deviations away from the mean?

Answer 1

whats the distance between 20 and 26?

Answer 2

6?

Answer 3

yes, now how many deviation is that distance?

n(sd) = 6

therefore

n = 6/(sd)

what is n?

Answer 4

0?

Answer 5

and no 6/(sd) is not 0

Answer 6

I dont know
