Although engineering has collected data on alternative process costs for building transmissions in the worksheet Transmission Costs, why did the engineers fail to reach a conclusion as to whether one of the proposed processes is better than the current process? Use confidence intervals to answer this question.

State the type of hypothesis test conducted

Explanation of why you chose the hypothesis test

State your hypothesis

Determine whether you reject or fail to reject the null hypothesis

Interpret your results (What does it mean to reject or fail to reject the null hypothesis in the context of the problem?)
