A researcher collects the following data from 5 college students regarding the number of times they drank alcohol in the last 30 days. We know that the population of college students drink a mean of 4.5 days in the last 30 days (i.e., this is the population mean). Is the mean level in the sample significantly different from the population mean? SPSS only. What significance test did you use? Cut and paste the output and interpret it in terms of significance and effect size.

can you tell me what significance test to use and how to calculate the effect size?
