Given a normal distribution with μ=50 and σ=5, and given you select a sample of n=100, complete parts (a) through (d).
d. There is a 40% chance that overbar X is above what value?
We are given that n=100, μ= 50 and σ= 5 , Now to calculate P( x̄ >50.7 ) we start by converting 50.7 to z score... View the full answer
- What what the answer be if its 35% chance?
