The probability statement that a student does not complete the exam in 130 minutes was determined to be P x 130 The corresponding probability statement for the normal random variable z is P Z 1 50 Recall that the normal probability table below gives the area under the curve to the left of a given z value and the entire area under this curve is 1 Here we want the area to the right of z 1 50 so we can subtract the area to the left of z 1 50 from 1 Z 0 00 0 01 0 02 0 03 1 4 0 9192 0 9207 0 9222 0 9236 1 5 0 9332 0 9345 0 9357 0 9370 0 9452 0 9463 0 9474 0 9484 0 9495 0 9505 0 9515 0 9525 0 9535 0 9545 0 04 0 05 0 9251 0 9265 0 9382 0 9394 0 06 0 07 0 08 0 9279 0 9292 0 9306 0 9406 0 9418 0 9429 0 09 0 9319 0 9441 1 6 Use the table excerpt above to find the probability that a student takes longer than 130 minutes to complete the exam rounding to four decimal places P Z 1 50 1 0 0495 X 0 0974 X
