What type of hypothesis test should be performed? Ex: Left-tailed z-test, unpaired t-test, paired t-test, or Two-tailed z-test

What is the test statistic? Ex: 0.123

What is the number of degrees of freedom? Ex: 25

Does sufficient evidence exist to support the claim that the voltage of the batteries made by the two manufacturers is different at the α=0.1 significance level? Ex: yes or no

The mean voltage and standard deviation of 11 batteries from each manufacturer were
measured. The results are summarized in the following table.
Manufacturer Sample mean voltage (millivolts) Sample standard deviatio
