A researcher is interested in whether early-risers (people who get up before the sun) have more optimism than the general population. The general population has a mean score of 8.8 on a validated optimism scale, with a standard deviation of 2.5. The sample used in the study has a mean of 9.5. The researcher computes the standard error of the mean to be .9643. What is the researcher's conclusion for this study?
