We give JMP output of regression analysis. Above output we give the regression model and the number of observations, n, used to perform the regression analysis under consideration. Using the model, sample size n, and output: Model: y = 60 + 61x1 + 62x2 + 633 + Summary of Fit RSquare RSquare Adj Root Mean Square Error Mean of Response Observations (or Sum Wgts) Sample size: n = 30 0.935808 0.928401 0.239937 8.382667 30 Analysis of Variance Sum of Source Model df Squares 3 21.820969 Error 26 1.496818 Mean Square 7.27366 0.05757 F Ratio 126.3447 C.

(Round your answer to 2 decimal places.) F(model) (5) Use the Amodel) statistic and the appropriate critical value to test the significance of the linear regression model under consideration by setting a equal to .05. HO: B1 B2 B3= 0 by setting a = .05. (6) Find the p-value related to Amodel) on the output. Using the p-value, test the significance of the linear regression model by setting a = .10, .05, .01, and .001. What do you conclude? p-value = 0000. Since this p-value is less than a =.001, we have that H0: B1 B2 B3 =0 is false. That is, we have that at least one of x1, x2,and x3is significantly related to y. evidence evidence
