3) What are the differences between correlation coefficient and regression coefficient? A study was [10.0] conducted among the households in a small city to determine what variables, if any, are related to the food expenditure of a household. Suppose the researcher wants to develop a regression model to predict the household level food expenditure by two variables, "family income" and "family size". The incomplete analysis of variance (ANOVA) table is given below- Degree of Sum of Mean sum of freedom (df) squares (SS) squares (MS) F Regression 2 52.7853 Residual 160.4294 Total 18 266 Complete the ANOVA table and comment on the overall significance of the regression model by F- test at 5% level of significance. Determine the coefficient of determination ( R2 ) and comment on it
