A sample has a mean of M = 25 and a standard deviation of s = 5. For this sample, find the X value corresponding to each of the following z-scores. (6 pts. total) z = 0.40 z = 1.20 z = 2.00 z = −0.80 z = −0.60 z = −1.40

Step 1
Step 1: Recall the formula to convert a z-score to an X value: \[ X = M + z \times s \] where \( M = 25 \) (mean), \( s = 5 \) (standard deviation), and \( z \) is the given z-score. Show more…

A sample has a mean of M = 25 and a standard deviation of s = 5. For this sample, find the X value corresponding to each of the following z-scores. z = 1.20, z = 2.00, z = 0.40, z = -0.60, z = -1.40, z = -0.80.

For a sample of n = 20 scores, X = 25 corresponds to z = -1.20 and X = 40 corresponds to z = +1.80. What are the values for the sample mean and standard deviation? M = 33 and s = 6 M = 30 and s = 6 M = 35 and s = 5 M = 31 and s = 5
