In a sample of 300 college seniors, 252 responded positively when asked if they have spring fever. Based upon this, compute a 95% confidence interval for th proportion of all college seniors who have spring fever. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) Lower limit: Upper limit: X 3
