Workers at a certain soda drink factory collected data on the volumes in ounces of a simple random sample of 21 cans of the soda to drink. Those volumes have a mean of 12.9 oz and a standard deviation of 0.12 oz and they appear to be from a normal distributed population. If the workers want the filling process to work so that almost all cans have volumes between 11.96 and 12.48 oz the range rule of thumb can be used to estimate that the standard deviation should be less than 0.13oz use the sample data to test the claim that the population of volumes has a standard deviation less than 0.13 oz use a significance level of 0.025
