The mean voltage and standard deviation of 5 batteries from each manufacturer were measured. The results are summarized in the following table. Sample mean Population standard voftage (millivolts) deviation[mil|ivolts) -- What tvpe of hvpothesis test should be performed? What is the test statistic? Ex: p.123 Left-tailed ztest Paired ttest What is the number of degrees of freedom? Ex: 25 Two-tailed 3'19\" Un paired ttest Does sufficient evidence exist to support the claim that the voltage of the batteries made bv the two manufacturers is different at the cc = {1.01 significance level?
