Draw a graph for the standard normal distribution. Label the horizontal axis at values of3,2,1, 0, 1, 2, and 3. Use thetable of probabilities for the standard normal distributionto compute the following probabilities. (Round your answers to four decimal places.)

(a)

P(z2.5)

(b)

P(z1)

(c)

P(1z1.5)

(d)

P(0 <z<2.5)
