Use the appropriate descriptive statistics from W2 Assignment 2. (See attached document)
- Assuming that the sample statistics you computed are exactly equivalent to the corresponding population parameters, identify the following:
- What score on Recall1 would correspond to an extremely high score?
- What score on Recall1 would correspond to an extremely low score?”
To find these hypothetical scores, solve for X (your raw score) using the following formula:
X = (±z)(sd) + M, where
z = The z-score cutoff for 5 percent in the tail (±1.645)
sd = Your sample standard deviation
M = Your sample mean
- Use Minitab to compute z-scores for Recall1. Complete the table, indicating the appropriate z-scores corresponding to each of the participants whose score is given. (See attached document)
