Laptop Battery Charge Time Narrative
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 random samples and computed the following summary information: Laptop Battery Charge Time Narrative 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 random samples and computed the following summary information: -Set up the rejection regions for the following testing conditions. Assume the assumptions of normality and equal variances are satisfied. a. . = 10, = 12, and = 0.05. b. . = 4, = 8, and = 0.01. c. . = 15, = 15, and = 0.05.
-Set up the rejection regions for the following testing conditions. Assume the assumptions of normality and equal variances are satisfied.
