From this, two 95% confidence intervals were computed: 20 30 40 Confidence Interval 1 Confidence Interval 2 (34.14, 46.18) (19.58, 60.74) 10 15 20 25 30 Proportion of County Residents with a College Degree Which of these two confidence intervals will capture the proportion of persons who voted for the Republican Presidential candidate in the last U.S. Presidential Election in this same county? Enter the correct values of the lower and upper bounds below. From this, the statistician wishes to estimate the statistical model yi = Bo+ Bititei Lower Bound = (use two decimals) where y; represents the proportion of person who voted for the Republican Presidential candidate in the most recent U.S. Presidential Election Upper Bound = (use two decimals) and ; represents the proportion of persons (who are at least 18 years of age) in the county who have a college/university degree.
