January 2nd, 2018
The 2002 GSS survey of American adult population found a mean age of 46.21 and a standard deviation of 17.45 for its sample of 1,496 adults. Assume that we know from census data that the mean age of all American adults is 43.10. Standard error is .45. Calculate the t statistic and test the null hypothesis at the .05 significance level. What is the t statistic? What is you decision about the null hypothesis? What does this tell us about how representative the sample is of the American adult population?
