thanks broThe probability of getting more than 1002mm, P(X>1002), is 225/900 = 1/4
Therefore, P(X < 1002) = 1 - 1/4 = 0.75
From the probability table, z = 0.674 (When probability is 0.75).
Standaridising,
(1002 - µ)/8 = 0.674
After doing the calculations, you'll get µ = 997.
Hope that helped
atleast urs must be better then mine
well
