Determine the area under the standard normal curve that lies to the left of (a) Z: 1.39, (D) Z: 1.49, {c122 1.99, and (d) 22 0.33. (a) The area to the left on= 1.39 is (Round to four decimal places as needed.) (b) The area to the left on = 1.49 is (Round to four decimal places as needed.) (c) The area to the left on= 1.09 is (Round to four decimal places as needed.) (d) The area to the left of Z = 9.33 is (Round to four decimal places as needed.)
