Heres the last question:
μ: $60k
σ: $5k
Assume that for the standard normal population the probability to not exceed 1.960 is 0.975
A.) Find the value V such that 97.5% of households have the income above (greater than V)
B.) Find the value U such that 2.5% of households have the income below (less than) U
C.) What is the proportion of households with the annual income between U and V
I have tried this a couple times, but everytime I check the answer it comes out wrong
Any help would be greatly appreciated
Thanks
