The following are the weights (kg) and blood glucose levels (mg/100 ml) of 16 apparently healthy adult males:

Weight (X) Glucose (Y)

64.0 108 75.3 109 73.0 104 82.1 102 76.2 105 95.7 121 59.4 79 93.4 107 82.1 101 78.9 85 76.7 99 82.1 100 83.9 108 73.0 104 64.4 102 77.6 87 Find the simple linear regression equation and test H0 : b1 ¼ 0 using both ANOVA and the t test. Test H0 : r ¼ 0 and construct a 95 percent confidence interval for r. What is the predicted glucose level for a man who weighs 95 kg? Construct the 95 percent prediction interval for his weight. Let a ¼ :05 for all tests.
