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.) USE SALT (a) P(X ≤ 17) (b) P(X 18.5) (c) P(X = 9.5) (d) P(15 ≤ x ≤ 20) (e) P(|X-17| ≤ 2)
