Amanufacturing firm claims that the batteries
used in their electronic games will last an average of
30 hours. to maintain this average, 16 batteries are
tested each month. if the computed t-value falls between
? t0.025 and t0.025, the firm is satisfied with its
claim. what conclusion should the firm draw from a
sample that has a mean of x = 27.5 hours and a standard
deviation of s = 5 hours? assume the distribution
of battery lives to be approximately normal.
