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. Complete parts a through c. Ll-ion NIMH Sample mean 96.2 82.1 Sample standard deviation 6.7 11.9 Sample size 14 17 a. Perform a hypothesis test using a = 0.10 to determine if the average number of minutes per charge diers between these two battery types. Assume the population variances for the number of minutes per charge are not equal. Determine the null and alternative hypotheses for the test. H0: 111 - [12 O H 13 P1 ' P2 0
