###### Question:

Jump to level 1 The mean voltage and standard deviation of 17 batteries from each manufacturer were measured. The results are summarized in the following table. 2 Manufacturer Sample mean voltage (millivolts) Sample standard deviatio А 171 B 169 3 What type of hypothesis test should be performed? Select What is the test statistic? Ex: 0.123 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 = 0.1 significance level?
