Suppose you study how much people like their jobs and hypothesize that it is related to occupational prestige. You sample 120 people and calculate an average occupational prestige score of 44 with a standard deviation of 2. Use this to calculate/answer the following:

1. Standard error of the mean
2. 95% confidence interval (CI)
3. 99% CI

You hypothesize that prestige may be related to race and find that your 80 white respondents averaged an occupational prestige score of 50 with a standard deviation of 3. Use this to calculate the following:

1. Standard error of the mean
2. 95% CI
3. 99% CI

Continuing your research on prestige and race, you find that your 40 non-white respondents averaged an occupational prestige score of 42 with a standard deviation of 1.5. Use this to calculate the following:

1. Standard error of the mean
2. 95% CI
3. 99% CI
