For a given large sample size, which of the following gives the smallest margin of error when calculating a confidence interval for a population proportion A. 93% confidence with p̂ = 0.34 B. 91% confidence with p̂ = 0.34 C. 95% confidence with p̂ = 0.18 D. 93% confidence with p̂ = 0.18 E. 91% confidence with p̂ = 0.18

Josh and Kendra each calculated a $90 \%$ confidence interval for the difference of means using a Student's $t$ distribution for random samples of size $n_{1}=20$ and $n_{2}=31 .$ Kendra followed the convention of using the smaller sample size to compute $d . f .=19 .$ Josh used his calculator and Satterthwaite's approximation and obtained $d, f . \approx 36.3 .$ Which confidence interval is shorter? Which confidence interval is more conservative in the sense that the margin of error is larger?
