A study by the University of Montreal examined a new test to deepen the evaluation of mental states through the creation and validation of a practical measure, the Mental States Task (MST). The researchers examined many factors, including age and the valid and reliable PANAS test. The data is in an excel file named "Montreal_Study_on_Mental_States" and is also in this week's assignment area. Using this data set, perform a correlation analysis using the subject's age ("AGE") as a predictor of their PANAS score ("PANAS") of all the subjects. Plot the data with a regression line and perform a regression with the appropriate statistical test in StatCrunch.Copy and paste your graph and regression output into your Word document for full credit. What is the correlation coefficient r,and what is the coefficient of determination here? What does the coefficient of determination mean in this case? Is there a statistically significant correlation between age and the PANAS score in this sample? What hypotheses did you test? Using StatCrunch, what is the predictedPANAS score for a subject that is 23 years old?
