Areas under the Normal Curve Use the standard normal table to find: • The z-score such that the area from the midpoint to z is 0.20. In the interior of the standard normal table, look up a value close to 0.20. The closest value is 0.1985, which occurs at z = 0.52. © 2002 The Wadsworth Group 20% of the area z
I Areas under the normal curve Use the standard normal table to find ° The probability associated with z:P(0≤z≤1.32) Locate the row whose header is 1. 3. Proceed along that row to the column whose header is. 02. There you find the value, 4066, which is the amount of area capture between the e mean and a z of 1.32 Answer:0.4066 1.32 o 2002 The Wadsworth Group
Areas under the Normal Curve Use the standard normal table to find: • The probability associated with z: P(0 z 1.32). Locate the row whose header is 1.3. Proceed along that row to the column whose header is .02. There you find the value .4066, which is the amount of area capture between the mean and a z of 1.32.
