A dietetics student wants to look at the relationship between calcium intake and knowledge about calcium in sports science students. Further she wants to know if knowledge about calcium can be used to predict calcium intake of the students. Table 1 shows the data she collected. Knowledge score (Out of Calcium intake (mg/day) Knowledge score (Out of Calcium intake (mg/ 50) 50) 10 450 38 940 42 1050 25 733 38 900 48 985 15 525 28 763 22 710 22 583 32 854 45 850 40 800 18 798 14 493 24 754 26 730 30 805 32 894 43 1085 If the goal is to learn about how knowledge about calcium is related to calcium intake in sports science students, which of these two variables is the response variable and which is the predictor variable? Find the following Compute the linear correlation coefficient r for this data set. Test for a significant linear correlation. Classify the direction and strength of the correlation. Direction: Strength: Equation of the least squares regression line. What is the valid prediction range for this setting? Test the significant of the regression line. What would you predict for calcium intake if the students score were 5? What would you predict for calcium intake if the students score were 35?
