Question 1.
**Educational Content on Z-Scores and Sample Analysis** 1) A sample has M = 22 and s = 4. In this sample, what is the X value corresponding to z = 1.44? 2) If an entire population with μ = 20 and s = 3 is transformed into z-scores, then the distribution of z-scores will have a mean of ___ and a standard deviation of ___. Explain. 3) What proportion of scores are between 14 and 19, based on the following sample: | 20 | 18 | 21 | |----|----|----| | 11 | 23 | 14 | | 16 | 22 | 12 | | 26 | 22 | 17 | **Explanation of Problem 3:** To find the proportion of scores between 14 and 19, identify the scores within the sample that fall within this range. Then, calculate the proportion based on the total number of scores provided.
