1. (1 point) State the topic variable (indicator) that you are using. Refer to the data catalog to understand the variable names. 2. (4 points) State the mean and standard deviation for both sexes for the variable of interest. Round the mean to the same number of decimal places as the observations. Round the standard deviation to one additional decimal place. 3. (4 points) Find 95% confidence interval (CI) for each. Explain the meaning of each confidence interval in English, referring to your variable name. You may use the TI calculator here. If you want to try it in Excel, instructions on how to calculate the margin of error in Excel are provided below. 4. (2 points) Did you calculate the Cls using the z-score (Z-interval) or the t-value (T-interval)? How did you decide which to use? 5. (2 points) Do the Cls overlap or not? What does that tell you about the difference or similarity between the sexes? In other words, do the confidence intervals provide evidence that the population parameter is different for males and females? Explain. 6. (3 points) Find 99% confidence interval (CI) for one of your variables (either male or female). Compare that to the 95% CI. Which is wider? Explain why one is wider than the other.
