Express the confidence interval (0.070, 0.126) in the form of p-E Solution 1 Let's find E 2E=(0.126-0.070) E=(0.126-0.070)/2 E=0.056/2 E=0.028 Solution 2 Let's find U u=(0.126+0.070)/2 u=0.196/2 u=0.098 Then: CI=(u-E < p < u+E) Replace the number according to the formula CI=(0.098-0.028 < p < 0.098+0.028)
