Can you help explain the what affects the width?

5. Based on the solved condence intervals below, explain what affects the width of a confidence interval (the difference between the upper and lower limits) and how. M=20 0:10 N=30 M=20 0:10 N=500 95% C|=Mt(1.96*oM) 95% c1=M(1.96*aM) =20:(1 95* 1.8257) =20i(1.96*0.4472) 95% Cl [16.42, 23.58] 95% Cl [19.12, 20.88] M=20 0:05 N=30 M=20 0:5 N=500 95% Cl=Mi(1.96*oM) 95% CI=M:(1.96*UM) =20:(1.95*0.0913) =2o:(1 .95*0. 0224) 95% Cl [19.82, 20.18] 95% Cl [19.96, 20.04]
