Document Summary
Stat 350 exam 2 review: sunday, november 9, 7 8:30 pm in mlb aud 3: jeff, fred, and suzie are all interested in comparing the average lifetime of generic batteries to that of brand name batteries. They each have their own theory they wish to test and selected the significance level they wish to use. The study involves letting a battery-powered cd player continuously play the same cd at a fixed volume and recording the time (in minutes) until no music is heard through the headphones. This process is followed for 6 sets of generic batteries (group 1) and 6 sets of brand name batteries (group 2). The resulting lifetime data were entered into spss to generate the output below. Jeff would like to assess if there is any difference between the average lifetime of generic batteries and that of brand name batteries.
