    Z is the standard normal random variable that is, the normal random variable with mean 0 and standard deviation 1. Use the table values in your textbook to determine the following

    a. The probability that z is less than -2.12.

    b. The probability that z is greater than 1.57.

    c. The probability that z is between -1.84 and 0.60.

    d. The value of z such that the area to the left of z is 0.4721.

    e. The value of z such that the area to the right of z is 0.9958.

    a. The probability that z is less than -2.12.
    Table gives the value of area under the curve between mean and Z value. So,
    P(Z<-2.12)=0.50-P(-2.12<Z<0)=0.50-0.4830=0.017

    b. The probability that z is greater than 1.57.
    Table gives the value of area under the curve between mean and Z value. ...
