The statsmodels ols method is used on a cars dataset to fit a multiple regression model using Quality as the response variable. Speed andAngie are used as predictor variables. The general form of this model is: f = pa -15peed*ldngfe If the level of significance, alpha. is 0.05. based on the output shown. what is the correct interpretation of the overall F-test? (Hint: Prob {F-statistic} is the P-value]. Select one. A text version of this output is available. O Null Hypothesis Ha: [31:32: 0 Alternative Hypothesis 3,: At least one Ii.- 7! t} for i=1, 2 P-value = 3.130e-13 Since the P-value is less than the level of significance. alpha, reject the null hypothesis. Conclude that at least one beta value is non-zero. Therefore, the model is statistically significant. 0 Null Hypothesis Ha: [31:31: 0 Alternative Hypothesis 3,: At least one I3.- a 0 for i=1, 2 P-value = 332.2 Since the P-value is greater than the level of significance, alpha, do not reject the null hypothesis. Conclude that all beta values are zero. Therefore, the model is not statistically significant. 0 Null Hypothesis 3,: [31:32: 0 Alternative Hypothesis 3,: At least one I3.- a t} for i=1, 2 P-value = 3.80e-13 Since the P-value is less than the level of significance. alpha, do not reject the null hypothesis. Conclude that all beta values are zero. Therefore, the model is not statistically significant. 0 Null Hypothesis Ha: [31:32: 0 Alternative Hypothesis 3,: At least one Ii.- 74 E} for i=1, 2 P-value = 332.2 Since the P-value is greater than the level of significance, alpha, reject the null hypothesis. Conclude that at least one beta value is non-zero. Therefore, the model is statistically significant. H.--...J.!....... E .'H ._ _.'._.-._
