An article reported data on potential drop measurements for one sample of connectors wired with alloy aluminum and another sample wired with EC aluminum. Does the accompanying computer output suggest that the true average potential drop for alloy connections (type 1) is higher than that for EC connections (as stated in
the article)? Carry out the appropriate test using a significance level of 0.01. [Note: The computer output reports the P-value for a two-tailed test.] (Use, for alloy connections and ₂ for EC connections.)
