For the following PAIRED OBSERVATIONS, calculate the 90% confidence interval for the population mean mu_d: A = {14.98, 13.37, 14.25, 15.32}, B = {10.61, 9.66, 11.03, 10.07}.

Your answer:
	3.29 < mu_d < 4.99
	3.16 < mu_d < 5.11
	2.69 < mu_d < 5.59
	3.55 < mu_d < 4.72
	4.06 < mu_d < 4.21
	2.53 < mu_d < 5.74
	2.68 < mu_d < 5.59
	2.70 < mu_d < 5.58
	3.10 < mu_d < 5.17
	3.81 < mu_d < 4.46
