Iowa normal distribution
WebFrom most tables you can see that 80 % of the area under the normal is to the left of 0.84. So by symmetry 80 % of the area is above − 0.84, and therefore 20 % of the area is below − 0.84. Note that the − 0.84 is approximate, That's a big hamburger. Should the question not be: find w such that P ( w e i g h t ≥ w) = 0.8. WebRevision Village - Voted #1 IB Math Resource!
