Correlation Matrix Correlation Matrix accuracy (wError) speed (sec) accuracy (%wError) Pearson's r p-value speed(sec) Pearson's r -0.552 - p-value 0.098\fQuestions 1. What is the value of the Pearson correlation coefficient? 2. In words, what does the correlation coefficient say about the relationship between the variables? Make sure to include both SIZE and DIRECTION of relationship. (For example, "There was a weak positive correlation between the variables such that as hours of study goes up, exam grade goes up.") 3. Is the correlation coefficient significant? (Use the same rule we've used in interpreting significance for the last two assignments. Assume an alpha level of 0.05.) How do you know? 4. In looking at the scatterplot, does the data look like they fit the line of best fit well or poorly? Justify your answer with a one-sentence explanation
