1) A distribution with μ = 15 and s = 3 is being standardized so that the new mean and standard deviation will be µ = 25 and s=5. When the distribution is standardized, what value will be obtained for a score of X = 8 from the original distribution? 2) A population of scores has μ = 24. In this population, a score of X= 14 corresponds to z = -1.35. What is the population standard deviation? 3) What proportion of scores are between 18 and 25, based on the following sample: 18 23 22 22 13 28 15 18 21 14 12 17

3) What proportion of scores are between 18 and 25, based on the following sample:
```
| 18 | 13 | 21 |
| 23 | 28 | 14 |
| 22 | 15 | 12 |
| 22 | 18 | 17 |
```
