A manufacturing firm claims that the batteries used in their electronic games will last an average of 28 hours. To maintain this average, 16 batteries are tested each month. If the computed t-value falls between - to.01 and to.01, the firm is satisfied with its claim. What conclusion should the firm draw from a sample that has a mea of x = 25.5 hours and a standard deviation of s = 5 hours? Assume the distribution of battery lives to be approximately normal. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. ..... Since the computed t-value t = does not fall between - to.01 = and to.01 = , the firm should be satisfied with the claim. (Round to three decimal places as needed.)
