Please anwser by hand! (By-Hand) A dietetics student wants to look at the relationship between calcium intake (g/week) and knowledge score about calcium in sports science students (knowledgescore out of 50). Further she wants to know if knowledge about calcium can be used to predict calcium intake of the students. The table below shows the data she collected.Knowledge Score38254828224118263043319Total:Calcium Intake9.407.339.857.635.838.107.987.748.0510.8582.76Part b:Compute Sxx, Syy, and Sxy for the above data.

The data shows the knowledge score and calcium intake.Part a: The scatterplot is drawn by labeling the x-axis as knowledge score with range of 10 to 50 (interval of 5) and y-axis as calcium intake with range of 4 to 12 (interval of 1), now the intersection of x and y are plotted in the graph as shown below:Part b: The value of Sxx is, Sxx=∑x2-∑x2n=11071-319210=11071-10176.1=894.9 Thus, the value of Sxx is 894.9. The value of Syy is, Syy=∑y2-∑y2n=703.0402-82.76210=703.0402-684.92176=18.11844 Thus, the value of Syy is 18.11844. The value of Sxy is, Sxy=∑xy-∑x∑yn=2740.2-319×82.7610=2740.2-2640.044=100.156 Thus, the value of Sxy is 100.156.Part c: The correlation coefficient is, r=SxySxxSyy=100.156894.9×18.11844=100.156127.334959677=0.7866 Thus, the correlation coefficient is 0.7866. It is clear that the correlation value 0.7866 shows that there would be strong positive correlation between the knowledge score and calcium intake.
