25 fast please An electronics company advertises that their new cell phone battery lasts longer after charging than the previous battery. A consumer agency decides to check out the claim. From a random sample of 60 new cell phone batteries and 60 previous cell phone batteries the following results are produced: Length of time the battery lasts after charging: Sample size Sample mean xbar Sample standard deviation S New Cell phone battery 60 11.8 hrs 2.1 Previous cell phone battery 60 11.1hrs 1.8 25. At the 5% level of significance, the appropriate conclusion is: Group of answer choices The average length of time the battery lasts after charging is higher for the new battery than for the previous battery. The average length of time the battery lasts after charging is lower for the new battery than for the previous battery. The average length of time the battery lasts after charging is at least as high for the new battery than for the previous battery. The average length of time the battery lasts after charging is no higher for the new battery than for the previous battery.
