Question

See the attachment and help determine the correct response?

The mean voltage and standard deviation of 10 batteries from each manufacturer were measured. The results are summarized in the following table: | Manufacturer | Sample mean voltage (millivolts) | Population standard deviation (millivolts) | |--------------|----------------------------------|-------------------------------------------| | A | 121 | 1 | | B | 119 | 4 | ### Hypothesis Test Details **Question:** What type of hypothesis test should be performed? - Options provided: - Left-tailed z-test - Paired t-test - Two-tailed z-test - Unpaired t-test **Question:** What is the test statistic? Response area provided for input. **Question:** What is the number of degrees of freedom? Response area provided for input. **Question:** Does sufficient evidence exist to support the claim that the voltage of the batteries made by the two manufacturers is different at the \( \alpha = 0.05 \) significance level? Response area provided for input. ### Graphical Components - A table demonstrating comparison between two manufacturers, highlighting sample mean voltage and population standard deviation. - A dropdown menu is shown for selecting the type of hypothesis test.
