Using this study above I need help with indentifying the following things:

1. The purpose of the study.
2. Describe the sample and the population for the study.
3. Identify the independent and dependent variables (note that there may be more than 1 independent and dependent variable).
4. Determine the level of measurement used for each of the variables (e.g. nominal, ordinal, interval and/or nominal).
5. Give the researcher's hypothesis.
6. Identify what a Type I error and a Type II error would be in the context of their hypothesis.
7. Find a measure of central tendency used in the study for one of the variables and describe it (e.g. 'the researchers stated that the median for age was 55').
8. Find a measure of variability used in the study for one of the variables and describe it (e.g. 'the researchers shared that the variance for number of cigarettes smoked daily was 20').
