Find these probabilities for a standard normal random variable Z. Be sure to draw a picture to check your calculations. Use the normal table or software. (a) P(Z < 1.7) (d) P(Z >0.6) (b) P(Z > -1.1) (e) P(-1.1 ≤Z≤1.7) (c) P(|Z| < 1.2) (a) P(Z < 1.7) = 0.9554 (Round to four decimal places as needed.) (b) P(Z > -1.1) = 0.8643 (Round to four decimal places as needed.) (c) P(|Z| <1.2) = 0.7699 (Round to four decimal places as needed.) (d) P(|Z| >0.6)= 0.5486 (Round to four decimal places as needed.) (e) P(-1.1 ≤Z≤ 1.7)=| (Round to four decimal places as needed.)
