Question 978628
z=(x-mean)/sd
=(130-115)/8 =1.875
Probability z>1.875 (should be small): 0.0304

Similarly the next one is z between (-.625 and +1.125), as it is -5/8  and +10/8
That should be fairly large, and it is 0.6037
Lower than 100 is -1.875 for z, and that is the same as being greater than 130, or 0.0304
