A statistician is working for a beverage company who sells bottled water. Each bottle is supposed to contain 16.9 oz of water with a standard deviation of 0.1oz of water. To ensure quality control the researchers randomly selects a sample of 30 water bottles and finds the standard deviation to be 0.3oz of water. Use a 0.05 significance level to test the claim that the standard deviation of the amoumt of water in all 16.9 oz bottles of water is greater than 0.1oz.
