The 2020 General Social Survey contains information on the number of hours worked by a respondent each week. The mean number of hours worked per week is 44.56, with a standard deviation of 16.22. The sample size is 225. 8. Estimate the value of the standard error (2 pts). 9. Calculate a 90 percent confidence interval for these data (2 pts). 10. Provide a one or two sentence interpretation of this result (2 pts). 1 1. Using this data, provide a hypothetical numerical example which demonstrates that the precision of a confidence interval is in part a function of sample size (2 pts). 12. Using this data, provide a hypothetical numerical example which demonstrates that the precision of a confidence interval is a function of both sample size and the level of confidence (2 pts)
