Question:
The records of a casualty insurance company show that, in the past, it's clients have had a mean of 1.9 auto accidents per day with a standard deviation of 0.05. The actuaries of the company claim that the standard deviation of the number of accidents per day is no longer equal to 0.05. Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries claim. State the null and alternative hypothesis that we would use for the test.
