A cell phone manufacturer test the battery lifetime of its cell phones by recording the time it takes for the battery charges To run out while testers are streaming videos on the phones continuously. The manufacture claims that the population mean of the battery life terms of Alfonso through latest model is 5.93 hours. As a researcher for a consumer information service you want to test his claim. To do so you select a random sample 45 cell phones of the manufacturers latest model in record their battery lifetime. As soon as number population standard deviation of the battery life times for the cell phone model is 2.42 hours.Based on your sample of all the steps below to construct a 95% confidence interval for the population mean the battery life times for all phones with a manufacturers latest model (a) Click on "Take Sample" to see the results from your random sample of 45 phones of the manufacturer's latest model.Sample standardPopulation standarddeviationNumber of phonesSample meandeviationTake Sample455.492.152.42Enter the values of the sample size, the point estimate for the population mean, the population standard deviation, and the critical value you need for your95% confidence interval.
