Given that we are examining the relationship between two continuous variables (number of hours worked and level of stress), the appropriate statistical test would be a correlation analysis. Specifically, we would want to conduct a null hypothesis test on Pearson's r, which would allow us to determine whether there is a significant linear relationship between the two variables. The other options (independent t test, paired t test, and z test) would be appropriate for different types of data, such as comparing the means of two groups or testing a hypothesis about a population parameter.
