Find the two standard scores (z) that correspond to the following. (Enter your answers from smallest to largest. Give your answers correct to two decimal places.)

(a) The middle 72% of a normal distribution is bounded by them. and (b) The middle 83% of a normal distribution is bounded by them. and

Find P(-3.11 < z < 0.00). Find P(-2.49 < z < 1.46).

Find P(z < -2.27). Find P(z > 2.45).

Find the area under the standard normal curve between z = 0.83 and z = 2.24, P(0.83 < z < 2.24).
