(b) Finally, the researcher is interested in examining the regression model for knowledge, attitude and practices towards the COFLU-20. The following model was developed to forecast individual practices towards COFLU-20 using knowledge and attitude scores. P = a + B K + 3 A where P = Practice towards COFLU-20 score K = Knowledge towards COFLU-20 score A = Attitude towards COFLU-20 score The data are processed using MINITAB and the output in Exhibit 1 below was obtained: Exhibit 1 The regression equation is *** Predictor Constant SE 0.462 t-ratio 10.282 Coef 4.755 Knowledge Attitude 0.8 0.024 0.039 2.055 0.041 0.6 0.393 0.695 R-sq = 81.5% Analysis of Variance SOURCE Regression Error MS 19.03 8.333 DF 2 38.06 2.284 0.104 297 2474.887 Total 299 2512.947 ) Identify the dependent variable(s) and the independent variable(s). (ii) Is ð significant? Show proof of the testing process used to arrive at your decision. State what this means in terms of attitude and practices. (ii) What does the value of R-sq indicate? Comment on the value of R-sq.
