(b) What are the standard deviations of battery life for the two samples? (Round your answers to two decimal places.) Primary Use: Talking hours hours Primary Use: Internet (c) Conduct the hypothesis test and compute the p-value. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = Using a 0.05 level of significance, what is your conclusion? O Reject Ho. We can conclude that the population variance in battery hours of use for the talk time application is larger than the population variance in battery hours of use for the Internet application. O Do not reject Ho.
