Limestone samples are taken from three different sections of the mine. Even through heating process is designed to reduce percent of silica in limestone, it may be possible that variation due to initial condition of raw limestone result in quality issues. (FYI: Number of samples for such test is usually in 100s to account for inner-regional variability) Conduct Bartlett's test of the following data to determine whether variances are equal at a = 0.01.
