Draw a graph for the standard normal distribution. Label the horizontal axis at values of -3, -2, -1, 0, 1, 2, and 3. Then use the table of probabilities for the standard normal distribution inside the front cover of the text to compute the following probabilities.
a. P(z ≤ 1.5)
b. P(z≤1)
c. P(1≤z≤1.5)
d. P(0
