confidence interval‚ what is the value of t? For a 90 percent confidence interval‚ and df = 15‚ t= 1.753 d. Develop the 90 percent confidence interval for the population mean. Xbar = 60; s = 20; n = 16 Xbar ±t(s/√n) = 60 ± 1.753 (20/√16) = 60± 1.753 (5) = 60± 8.765 = [51.24‚ 68.77] e. Would it be reasonable to conclude that the population mean is 63 pounds?
