It is always good to have as narrow a confidence interval as possible, because a C.I. is an estimate of a parameter, and a narrower C.I. is a more precise estimate. In lecture we learned three factors that affect the width of a C.I. With all that in mind, which C.I. below has the combination that would make it the NARROWEST out of all four options?
Group of answer choices
A C.I. with n=55, 99% level of confidence, s = 20.4 (large standard deviation)
A C.I. with n=55, 95% level of confidence, s = 2.1 (small standard deviation)
A C.I. with n=45, 99% level of confidence, s = 2.1 (small standard deviation)
A C.I. with n=45, 95% level of confidence, s = 20.4 (large standard deviation)
