Question

IS Find the following probability for the standard normal random variable z. a. P(z<-1.02) b. P(z <2.03) c. P(0.68 szs2.03) d. P(-2.66szs1.56) a. P(z -1.02)(Round to four decimal places as needed.) b. Pize 2.03)=[] (Round to four decimal places as needed.) ook c. P(0.68 szs2.03) (Round to four decimal places as needed.) d.P(-2.66 s zs 1.56) = [□ (Round to four decimal places as needed.)

Answer 1

From the z table output, the required probabilities will be:

a) P(z < -1.02) = 0.1539

b) P(z < 2.03) = 0.9788

c) P(0.68 < z < 2.03) = 0.2271

d) P(-2.66 < z < 1.56) = 0.9367
