An experimenter would like to construct a 99% two-sided t-interval, with a length at almost 0.2 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 resistances is no larger than 0.15 ohms, what sample size would you recommend? assume that an appropriate t-value is 3.0.a. aprox 10b. aprox 20c. aprox 30d. aprox 40e. aprox 50
