5. People with diabetes must manage their blood sugar levels carefully. They measure their fasting plasma glucose (FPG) several times a day with a glucose meter. Another measurement, made at regular medical checkups, is called HbA. This is roughly the percent of red blood cells that have a glucose molecule attached. It measures average exposure to glucose over a period of several months. The table below gives data on both HbA and FPG for 14 diabetics five months after they had completed a diabetes education class. 5 6 7 89 10 11 1 2 3 4 12 13 14 7.3 7.5 HbA (%) 6.4 6.2 6.4 6.4 7.3 7.3 7.5 87.8 9.2 9.110.2 10.2 68.9 FPG 142 361 112 155 130 92 92 79 149 176 184 188 180 202 (mg/ml)y Make a scatterplot with HbA as the explanatory variable and observe the character of the relationship between sets of data. Which data point (of columns 1-14) is an outlier in the x direction? Give your answer as the column number. Which data point (of columns 1-14) is an outlier in the y direction? Give your answer as the column number. Calculate the correlation ( 0.01) with the outliers in the data: Calculate the correlation (± 0.01) without the outlier in the x direction in the data: Calculate the correlation (± 0.01) without the outlier in the y direction in the data:
