One way to check on how representative a survey is of the population from which it was drawn is to compare various characteristics of the sample with the population's characteristics. A typical variable used for this purpose is age. The 2002 General Social Survey of the U.S. adult population found a mean of 46.21 and a standard deviation of 17.45 for its sample of 1,496 adults. Assume we know from U.S. census data that the mean age of all U.S. adults is 43.10. Of the tests of statistical significance you have learned in this course, the one that would be most appropriate for checking on how representative the 2002 General Social Survey is of the U.S. adult population using age is the one-sample t test. The research hypothesis is

A. = 43.10.

B. > 43.10.

C. < 43.10.

D. 43.10.

none of the above
