Normal Distribution Calculations Using Technology

It will often be necessary to calculate probabilities of the form P(Z z), P(Z z), or P(a Z b), where Zhas a standard normal distribution. Microsoft Excel: Using Microsoft Excel, you can nd probabilities of the form P(Z z). For example, to nd P(Z 1:26), type \=normsdist(1.26)" into a cell, and you should get .8962. ................
