An experimenter would like to construct a 95% two-sided t-interval, with a length at most 0.5 ohms, for the average resistance of a segment of copper cable of a certain length. If the experimenter feels that the standard deviation of such resistance is no longer than 0.25 ohms, what sample size would you recommend?
