I answered the box where I filled in the blanks, but the next 2 parts confuse me!

Part I. Data were collected for the weight (X1), age (X2), smoking status (X3) and plasma lipid levels of total cholesterol (Y) for a hypothetical sample of 45 patients suffering from hyperlipoproteinemia, before drug therapy. 1[4 pts]. Complete the following ANOVA table (Table 1) when regressing Y on the three independent variables using the collected data. Table 1: See R2 Model 111390.5a__ 37296.36_ {1.169695 Error 33479.46 797_J___ Corrected Total 145370.04 2. [4 pts]. Based on the filled information in Table 1, conduct the overall test. [State the null and alternative hypothesis, test statistics and its value for the F test. Use rejection region or p-value to draw a conclusion about the F test.] 3. The sum of squares for the regression model in Table 1 is further decomposed into the following three terms (Table 2), which corresponds to the results obtained from a variables-added-in-order regression analysis
