MATH1342 PROJECT (LAB) 6 – CHAPTERS 7 & 8 NAME: ________________ Collin County College Fall 2011 Instructor: Daryl Rupp DUE DATE: 10/11/2011 Part I. (Use the calculator) Round the probabilities and Z-Values to the third decimal place. We know that 68.26% of the area lies between z = -1 and z = +1 for the standard normal distribution curve. This means that the probability of picking a number between -1 and 1 (from a standard normal distribution) is 0.6826. Find the probability of picking a number between, greater to or less than Z Value(s) below, from a standard normal distribution. Use the graphs on page 3 to mark and shade the areas represented by the probabilities of 1 thru 10. 1. z = -0.5244 and z = 0.5244 so the probability (area) is: 2. z = -0.6745 and z = 0.6745 so the probability (area) is: 3. z = -1.2816 and z = 1.2816 so the probability (area) is: 4. z = -1.6449 and z = 1.6449 so the probability (area) is: 5. z = -2.5758 and z = 2.5758 so the probability (area) is: 6. z > -1.2816 so the probability (area) is: 7. z < -2.5758 so the probability (area) is: 8. Z > 0 so the probability (area) is: 9. Z > 2.5758 so the probability (area) is: 10. Z > 1.6449 so the probability (area) is:
