Carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal places.

Let Z be a standard normal random variable. Use the calculator provided to determine the value of such that?
P( -c %26lt; Z %26lt; c ) = P( Z %26lt; c ) - P (Z %26lt; -c ) = P( Z %26lt; c) - [ 1- P( Z %26lt; c ) ] (due to symmetry)





= 2 P( Z %26lt; c ) - 1 = 0.9439





P( Z %26lt; c ) = 1.9439 / 2 = 0.97195





c = inverse of standard normal distribution at 0.97195 = 1.910258.
