Question

What type of hypothesis test should be performed? Ex: Left-tailed z-test, Left-tailed t-test, Right-tailed t-test, or a Two-tailed z-test.

What is the test statistic? Ex: 0.12

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? Ex: yes or no

An electrician wants to know whether batteries made by two manufacturers have
significantly different voltages. The voltage of 150 batteries from each manufacturer
were measured. The population standard deviations of the voltage for each
manufacturer are known. The results are summarized in the following table.
