Post by: Stevbo on Aug 15, 2016 The ABC battery company claims that their batteries last 100 hours, on average. You decide to conduct a test to see if the company's claim is true. You believe that the mean life may be different from the 100 hours the company claims. You decide to collect data on the average battery life (in hours) of a random sample of n = 20 batteries. Some of the information related to the hypothesis test is presented below.
Test of H0: mu = 100 versus H1: mu /= 100 Sample mean 98.5 Std error of mean 0.777 Assuming the life length of batteries is normally distributed, what is the p-value associated with this test? Place your answer, rounded to 3 decimal places in the blank. For example, 0.234 would be a legitimate entry. Title: Re: The ABC battery company claims that their batteries last 100 hours, on average.
