Question
Just D and E
Suppose the force acting on a column that helps to support a building is a normally distributed random variable X with mean value 17.0 kips and standard
deviation 1.50 kips. Compute the following probabilities by standardizing and then using a standard normal curve table from the Appendix Tables or SALT.
(Round your answers to four decimal places.)
In USE SALT
(a) P(X s 17)
0.5000
(b) P(X s 18.5)
0.8413
(c) P(X 2 9.5).
