I actually have no idea how to work these problems. I don't even know how to start.

### PSYS 313: Homework 2 - One Sample Tests and Stuff 1. **Hypothesis**: Reality TV watchers differ from the population in emotional intelligence. - **Data**: - Sample Mean (\( \bar{X} \)) = 102.5 - Sample Standard Deviation (\( S_X \)) = 18 - Sample Size (\( N \)) = 144 - Population Mean (\( \mu_c \)) = 100 - Population Standard Deviation (\( \sigma \)) = 15 2. **Hypothesis**: College students sleep less than the recommended 8 hours. - **Data**: - Sample Mean (\( \bar{X} \)) = 7.25 - Sample Standard Deviation (\( S_X \)) = 2.1 - Sample Size (\( N \)) = 25 3. **Task**: Compute a confidence interval (95% interval, 2-tailed) for a mean. - **Data**: - Sample Mean (\( \bar{X} \)) = 38.5 - Sample Standard Deviation (\( S_X \)) = 8 - Sample Size (\( N \)) = 22 *Note: There are no graphs or diagrams to explain in this document.*
