Statistics? I thought it was .92 because .8212 is closest on the table but thats wrong?

z table normally gives a left -tail 

P(z< Z) = left-tail 

P(z>Z) = 1- P(z<Z) is the right tailed 

so you need to look up 

P(z<Z) = 1-0.8225 =   0.1775

https://www.math.arizona.edu/~rsims/ma464/standard...

P(z< -0.93) = 0.17619    (so 0.1775 is 0.131 away from this) 

P(z< -0.92 ) = 0.17879   (so 0.1775 is 0.129 away from this) 

so the answer should z = -0.92  ��( not + 0.92) 

but is  really closer to -0.925  

Since 0.8225 is more than 0.5 and applies to the right-area, the z value applies to a  value *below* the mean and you might be expected to enter a negative value, i.e. -0.92
