10. Find the proportion of the normal distribution that is located between the following z- score boundaries: 1. Between z = 0.25 and z = 0.75 2. Between z = 0 and z = 1.50 3. Between z = -1.00 and z = 1.00 4. Between z = -0.75 and z = 2.00
(NOTE: You are do this by BY HAND using Table B.1 - The Unit Normal Table)
10. Find the proportion of the
1. Between z = 0.25 and z = 0.75
2. Between z = 0 and z = 1.50
3. Between z = -1.00 and z = 1.00
4. Between z = -0.75 and z = 2.00
11. Find the following percentile and percentile ranks for a normal distribution with a mean of ? = 120 and ? = 15.
1. The 15th percentile 2. P88
3. The percentile rank for X = 142
4. The percentile rank for X = 102
5. The percentile rank for X = 120
6. The
12. For a normal distribution with a mean of ? = 120 and ? = 20
1. What z-score separates the top 40% (highest scores) from the rest?
2. What z-score corresponds to the 90th percentile?
3. What raw score correspond to the 90th percentile?
4. What range of scores would form the middle 60% of this distribution?
