An engineer is comparing voltages for two types of batteries (K and Q) using a sample of 66 type K batteries and a sample of 41 type Q batteries. The mean voltage is measured as 9.38 for the type K batteries with a standard deviation of 0.648, and the mean voltage is 9.53 for type Q batteries with a standard deviation of 0.658. Conduct a hypothesis test for the conjecture that the mean voltage for these two types of batteries is different. Let μ1 be the true mean voltage for type K batteries and μ2 be the true mean voltage for type Q batteries. Use a 0.02 level of significance.
Step 1: State the null and alternative hypotheses for the test Step2: Compute the value of the test statistic. Round your answer to two decimal places Step 3: Determine the decision rule for rejecting the null hypothesis Ho. Round the numerical portion of your answer to two decimal places Step 4: Make the decision for the hypothesis test
