Assume that the readings on a pulse oximeter are of a standard normal distribution having a mean of 0. An oximeter is randomly selected and tested. In each case, 1) first diagram (draw) and 2) then calculate the final probability in decimals to 3 significant figures of each reading. 1. A standard normal distribution with a z-score greater than 1.28

2. A standard normal distribution with a z-score less than -0.92 3. A standard normal distribution with a z-score between -0.65 and 1.34
