We can now create our confidence interval for the proportion of college students who have a high level of stress. A sample of 253 253 college students was collected and found that 56 56 of them had high levels of stress. We found the margin of error to be 0.0588 0.0588. (a) Find the lower bound of the confidence interval. Round to 4 4 decimal places. Lower bound = (b) Find the upper bound of the confidence interval. Round to 4 4 decimal places. Upper bound =
