A science teacher performs a regression analysis to find out whether the test score obtained during Mid-term Theory Test explains the marks obtained for the Year-end Lab Test. The sample data are shown as follows: Theory Test Lab Test 50 3 39 5 7 9 98 12 68 1 1 91 10 56 4 Answer the following questions. (a) The independent variable is 'Mid-term Theory Test' (Key in either True or False) True (b) The value of XX is 477 (c) The value of [y is 54 (d) The value of ny is 4078 (e) The value of sz is 35291 (f) The regression equation is fzb0+ 17 1x. (f) The regression equation is 7=b0+ I; 1x. Fill in the b0 and D1 in three decimal places: (9) The correlation coefficient is found to be 0.847. We can say that the linear relationship between the Mid-term Theory Test and the Year-end Lab Test is: (Choose one to key in: negative / positive / zero) (Choose one to key in: weak/ moderate / strong) (h) The coefficient of determination is , in three decimal places
