An electrician wants to know whether batteries made by two manufacturers have significantly different voltages. The voltage of 50 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. Manufacturer Sample mean voltage (millivolts) Population standard deviati A B 130 129 What type of hypothesis test should be performed? Select What is the test statistic? Ex: 0.12 1 4 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
Plz answer all asap
In creating the null hypothesis for a hypothesis test for the standard deviation, it is wrong to write s = 30. Why is this so? ○ It just doesn't look and feel right. O Because my professor said so. O It should be the inequality sign, and not the equality sign. O Because hypothesis statements are about the popula- tion and not about the sample.
