he 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.

No – the claim is the null hypothesis and I rejected the null hypothesis. Yes – the claim is the alternate hypothesis and I rejected the null hypothesis. Yes – the claim is the alternate hypothesis and I rejected the null hypothesis. No – the claim is the alternate hypothesis and I failed to reject the null hypothesis. No – the claim is the alternate hypothesis and I failed to reject the null hypothesis.

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?
