A manufacturing firm claims that the batteries used in their electronic games will last an average of 30 hours. To maintain this average, 25 batteries are tested each month. If the computed t-value falls between to.015 and t0.015, the firm is satisfied with its claim. What conclusion should the firm draw from a sample that has a mean of x = 31.6 hours and a standard deviation of s=4 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= between 0.015 and t0.015= = the firm should satisfied with the claim. (Round to three decimal places as needed.) = between t0.015 and t0.015 = , the firm should Since the computed t-value t= (Round to three decimal places as falls does not fall satisfied with the claim. Since the computed t-value t= (Round to three decimal places as needed.) Enter your answer in each of the answer boxes between -0.0151 = and to.015 = the firm should satisfied with the claim. not be be
