Question: In Chapter 8 (Task 9) we looked at data based on findings that the number of cups of tea drunk was related to cognitive functioning

In Chapter 8 (Task 9) we looked at data based on findings that the number of cups of tea drunk was related to cognitive functioning (Feng et al., 2010). Using a linear model that predicts cognitive functioning from tea drinking, what would cognitive functioning be if someone drank 10 cups of tea? Is there a significant effect? (tea_716.sav)

Chapter 8 Task 9

The research in the previous task was replicated but in a larger sample (N = 716), which is the same as the sample size in Feng et al.’s research (tea_716.sav). Conduct a correlation between tea drinking and cognitive functioning. Compare the correlation coefficient and significance in this large sample, with the previous task. What statistical point do the results illustrate?
