Using the sample data collected (see attached), consider the variables (satisfaction with job and satisfaction with the economy) and perform the following:
1. Determine what scores correspond to the top and bottom 10% and 25% of the data.
Begin with the z-score formula and transform the formula so that you are solving for the individual score (denoted as X in the z-score formula).
2. Determine the z-score that corresponds to the top 10% and then substitute in your values for the mean and the standard deviation. Repeat the steps for the bottom 10% and then the top and bottom 25%.
3. Determine what percentage will be between 3 and 7 for both variables (these scores correspond to ratings of somewhat satisfied to somewhat dissatisfied and exclude the extreme ratings of extremely satisfied and extremely dissatisfied).
Start with the z-score formula and calculate the z-score for each value. Explain the process for converting a z-score to a percentile.
4. Determine what scores correspond to the top and bottom 10% and 25% of the data.
5. Transform the z-score formula for solving for the individual score.
6. Determine the z-score that corresponds to the top 10% and substituted in your values for the mean and the standard deviation. Repeat the steps for the bottom 10% and the top and bottom 25%.
7. Determine what percentage will be between 3 and 7 for both variables.
Compute the z-score for each value. Explained the process for converting a z-score to a percentile.
