An engineer is comparing voltages for two types of batteries (K and Q) using a sample of 71 type K batteries and a sample of 50 type Q batteries. The mean voltage is measured as 9.33 for the type K batteries with a standard deviation of 0.153. and the mean voltage is 9.68 for type Q batteries with a standard deviation of 0.366. Conduct a hypothesis test for the conjecture that the mean voltage for these two types of batteries is different. Let a, be the true mean voltage for type K batteries and Hz be the true mean voltage for type Q batteries. Use a 0.05 level of significance. Step 1 of 4: State the null and alternative hypotheses for the test. Answer Tables Keypad Keyboard Shortcuts Ho P
