At 0.01 level ofsignificance since p-value is less hence we reject the NULL hypothesis. Part bThere are 4 groups in the above problem. Number of Groups = degrees of freedom (between treatment) + 1 = 3+1 = 4Part cThere are 21 observations in the above problem. Number of observations = degrees of freedom (within treatment) + 1=20+1 = 21Answer 2Table 2: Coefficients of Regression EquationCoefficientsStandard Errort StatP-valueIntercept13613.769.8810.000Year (t)39.182.2217.6640.000From table 2 the trend of the number of units sold by the auto manufacturer can be written as: Number of Units sold (000s) = 136 + 39.18*YearThus, in the 11th year the number of units sold = 136+39.18*11 = 566.98 ≈ 567 (000s)
