Question
The manufacturer of a particular vacuum cleaner estimates that the mean length of time before the main belt needs replaced is at least 27 months. A random sample of 25 of their vacuum cleaners found a mean length of time prior to belt replacement of 25.9 months, with a standard deviation of 4.8 months. At ? = .05, can you support the manufacturer’s claim?
