Question
questions: The statistics you just reported in parts i., ii., iii., and iv. above can all be interpreted in the context of this regression model. Match each statistic to a valid interpretation. Note that two will not be used.
i.________
ii._________
iii.________
iv._________
(A: the probability we would calculate a slope at least as big as the one we calculated if the population slope were zero.
B: how many times bigger the estimated slope was than its standard error
C: the number of extra votes for Buchanan that our model would predict for each additional person who voted in the election.
D: the number of votes for Buchanan that our model would predict if no one had voted in the election.
E: the proportion of the variability in votes for Buchanan across counties that can be attributed to differences in the total number of votes cast.
F: the number of voters who voted for someone other than Buchanan, for each voter who voted for Buchanan.)
b. Report the following summary statistics from JMP i. bo: 56.2942(report to exactly four decimal places) ii. bi : 0.0023 (report to exactly four decimal places) ii. R2: 0.4593 iv. The statistic that tests H 0: 1 = 0 7.43Explanation / Answer
1) b0 is intercept ,occurs in the regression equation when variable for beta1 is zero
D: the number of votes for Buchanan that our model would predict if no one had voted in the election.
2 ) beta 1 is slope
C: the number of extra votes for Buchanan that our model would predict for each additional person who voted in the election.
3) r2 is variability explained by the model
E: the proportion of the variability in votes for Buchanan across counties that can be attributed to differences in the total number of votes cast.
4)
B: how many times bigger the estimated slope was than its standard error
