Suppose the force acting on a column that helps to support a building is a normally distributed random variableXwith mean value13.0kips and standard deviation1.50kips. Compute the following probabilities by standardizing and then using a standard normal curve table from theAppendix Tablesor SALT. (Round your answers to four decimal places.)

(a)

P(X13)

(b)

P(X14.5)

(c)

P(X5.5)

(d)

P(11X16)

(e)

P(|X13|1)
