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
