The average age for all voters in the United States is 44.5. Does the mean age of our sample of voters significantly differ from the population mean? Determine the correct type of test to run to assess this question and conduct it.  In this text box, report your results in APA format, including whether the results were significant (with df, t and p values), the mean and standard deviation, and your conclusions.
