QUESTION 4 a) Previous research reported that a fasting blood glucose level is dependent to body mass index (BMI). A new study was conducted by Hospital Everjaya to determine the relationship between body mass index and fasting blood glucose levels of diabetic patients in Hospital Everjaya. The data collected is shown as below. Body mass index Fasting blood glucose (kg/m) levels (mg/dL] 26 130 30 120 35 120 22 90 38 130 19 75 21 83 32 100 1) Construct a scatter diagram for the above data. (3 marks) ii) Calculate the Pearson product moment correlation coefficient, Interpret the value obtained. (5 marks) b) Research has shown that caffeine is quite effective in managing and reducing one's anxiety symptoms. Based on that, a researcher plans to investigate whether caffeine consumption influence students' anxiety scores. The MINITAB output on caffeine consumption (in milligram) and anxiety scores is shown below.
