#1. (15 points) Researchers wanted to compare memory (0-50 scale; lower scores = lower memory) in a sample of 30 smokers (M = 38.89) to the population of non-smokers with the mean of 43.78 and a variance of 14.27. Conduct a one-sample z-test: calculate a z-score, include your calculations for both SEM and z-score. Write an apa-style report for a one-tailed one-sample z-test you conducted. Follow the apa-style report template provided in Lecture 09. Note that all statistical parameters should be reported in italic.
#2. (15 points) Researchers wanted to compare depression scores (0-100 scale; lower scores = lower depression) in a sample of 36 student athletes (M = 58.32) to the general population of non-athlete students with the mean of 61.14 and a standard deviation of 13.52. Conduct a one-sample z-test: calculate a z-score, include your calculations for both SEM and z-score. Write an apa-style report for a two-tailed one-sample z-test you conducted. Follow the apa-style report template provided in Lecture 09. Note that all statistical parameters should be reported in italic.
