The following is the ANOVA obtained from a regression analysis:ANOVASource of VariationREGRESSIONERRORTOTALDegree ofFreedom170===Sum ofSquares14.5387.7===Mean Squares======F-calculated===Your are interested to evaluate the following hypothesis:Ho: B 1 B 2 ---against--- HA: B1 B21. How many observation were used in this experiment? (place your answer in the box below)2. Evaluate the F calculated for the regression, and indicate if you are going to reject(R) or fail to reject(R) the null hypothesis usingan a = 0.05 (R/FR; place your answer right beside the calculated number of treatments)

Given: We need to complete the ANOVA table that has partial information. dfreg=1dferror=70SSR=14.5SSE=387.7The complete ANOVA table is given as; SV df SS MSS F Regression p=1 14.5 =SSRdfreg=14.5 =MSRMSE=2.61800361 Error N-(p+1)=70 387.7 =SSEdferror=5.538571 Total N-1=71 402.2 1) Total number of observations used in the experiment were N=72. 2) F=MSRMSE=2.61800361≅2.62 Critical F=3.9778 Critical value of F at α=0.05 is calculated using the EXCEL function as shown in the snip below. Decision: Calculated F< Tabulated F We fail to reject the null hypothesis at 5% level of significance.
