The following table shows the results of two random samples that measured the average number of minutes per charge for AA Lithium-ion (Li-ion) rechargeable batteries versus Nickel-Metal Hydride (NiMH) rechargeable batteries. Perform a hypothesis test using α =0.05 to determine if the average number of minutes per charge for Li-ion batteries last longer than NiMH batteries. Assume the population variances for the number of minutes per charge are unequal.
