The area under a normal curve is ______. 3. The area under a normal curve may also be expressed in terms of _ or __or___. 4. The measure of the mean, the median and the mode of a normal curve are ___. 5. The skewness of a normal curve is 0 because it is a/an ___________shape. Find the corresponding area between z=0 and each of the following z-values: 1. z =1.75 2. z =-2.58 3. z = 1.32 Determine each of the following areas and show these graphically. Use probability notation in your final answer. 1. At most z = 1.46 2. Between z=-0.78 and z=-1.95 Find each of the following percentile points under the normal curve. Complete your procedures and find the corresponding z-score of each problem. 1. P99 2. P32 Given μ=62 and =8, find the z-score up to two decimal place that corresponds to each of the following raw scores. 1. X=82 2. X=42
