The standard deviation of fill volume of a container of a pharmaceutical product must be less than 0.2 oz to ensure that the container is accurately filled. Six independent samples were selected, and the statistical hypotheses about the standard deviation were tested. The P-values that resulted were 0.15, 0.091, 0.075, 0.02, 0.04, and 0.06. Is there sufficient evidence to conclude that the standard deviation of fill volume is less than 0.2 oz?
