As an owner of a business, having a consistent level of sales
is important. Prior to the recession that started in 2007, the
standard deviation of the sales of a local business was $474. In a
sample of 28 weeks since the start of the recession, sales have
averaged $6800 per week with a standard deviation of $892. When
testing the hypothesis (at the 5% level of significance) that the
variance is higher than it was pre-recession, what is the test
statistic? (please round your answer to 2 decimal places) ***PLEASE
