4. A scale measuring trust in the media was administered to a random sample of 114 Democrats and 112 Republicans. The researcher finds that Democrats average a score of 8.5 on this scale, while Republicans average a score of 7.8. Together the Democrats and Republicans have a pooled standard error of .32. Is there a statistically significant difference between Democrats and Republicans in their level of trust in the media (at the alpha=.05 level)? Hint: Follow the 5 step method for hypothesis testing. Make sure that you show the results of your t tests and interpret your results in terms of the original research question.
