You can put this solution on YOUR website!
z = (x - mu)/(sigma)

z = (x - 100)/(8)

-------------------------------------------------------------

z score for x = 98

z = (x - 100)/(8)

z = (98 - 100)/(8)

z = (-2)/(8)

z = -0.25
-------------------------------------------------------------

z score for x = 108

z = (x - 98)/(8)

z = (108 - 100)/(8)

z = (8)/(8)

z = 1

-------------------------------------------------------------

z score for x = 112

I'll let you do this one
