Question 200765
A normal distribution has a mean of 80 and a standard deviation of 14. Determine the value above which 80% of values will occur
-----------------
The z-value for 80% is inVNorm(0.8) = 0.841621...
-----------------
Use the formula x =z*s + u to solve for "x":
x = 0.841621*14 + 80
x = 91.783
