A computer laboratory manager was in charge of purchasing new battery packs for her lab of laptop computers. She narrowed her choices to two models that were available for her machines. Since the models cost about the same, she was interested in determining whether there was a difference in the average time the battery packs would function before needing to be recharged. She took two independent samples and computed the following summary information: 
Perform the appropriate test of hypothesis to determine whether there is a significant difference in average functioning time before recharging between the two models of battery packs. Test using 
= 0.10.
Test statistic = ______________
Critical Value(s) = ______________
Conclusion: ______________
Interpretation: __________________________________________
Find the p-value for the test above.
p-value = ______________
Hypothesis Test
An analytical technique in statistics that uses data gathered from a small group to investigate a claim about a characteristic of the larger population.
Battery Packs
Assemblies of batteries or cells arranged together to provide a specific voltage, capacity, or power level.
Functioning Time
The duration in which a system or device operates effectively without failure.
- Execute and elucidate the results from hypothesis tests regarding disparities among two population means, employing sample information.
- Evaluate assertions and reach conclusions through p-value and significance level benchmarks.
