An engineer is comparing voltages for two types of batteries (K and Q) using a sample of 70 type K batteries and a sample of 83 type Q batteries. The mean voltage is measured as 9.13 for the type K batteries with a standard deviation of 0.330, and the mean voltage is 9.51 for type Q batteries with a standard deviation of 0.238. 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 3 of 4 : Determine the decision rule for rejecting the null hypothesis H0. Round the numerical portion of your answer to two decimal places.
