Question

Let Z be a standard normal random variable. Calculate the following probabilities using the ALEKS calculator. Round your responses to at least three decimal places.

Answer 1

(a)

P (Z > -1.62 ) = 0.94738

(b)

P (Z ≤ 1.72) = 0.95728

(c)

P (-058 < Z < 1.91 ) = 0.69097

Z<1.91 = 0.97193

Z<-0.58 = 0.28096

0.97193 - 0.28096 = 0.69097
