The mean voltage and standard deviation of 6 batteries from each manufacturer were measured. The results are summarized in the following table. Manufacturer Sample mean voltage (millivolts) Population standard deviation(millivolts) A 109 1 B 105 3 What type of hypothesis test should be performed Select Left-tailed z-test What is the test statistic? Ex: 0.123 0 Paired t-test Two-tailed z-test Unpaired t-test What is the number of degrees of freedom? Ex: 250 Does sufficient evidence exist to support the claim that the voltage of the batteries made by the two manufacturers is different at the a = 0.05 significance level? ( Select ,
