Independent random samples from two different populations that are approximately normally distributed yield the following data. Although they are unknown, the two population standard deviations are assumed to be equal to each other. 151: 114 , E2 = 115.2 , S1 = 9.6, 82 = 1, m = 27, 9'12 2 1].. Construct a 80% confidence interval for the difference of the population means, #1 pig . Round your answers to 3 places after the decimal point, if necessary. If it is not appropriate to construct a confidence interval in this situation, then enter "0" in both answer boxes below. 8053 confidence interval: [
