An automatic filling machine is used to fill Tide pods with liquid detergent. A random sample of 20 Tide pods results in a sample variance of fill volume of s²= (0.0153)² (fluid ounce). If the variance of the fill volume is too large, an unacceptable proportion of pods will be under- or overfilled. If we assume that the fill volume is approximately normally distributed, calculate a 95% confidence interval on the variance of the pod fill volume.

Suppose the following values are obtained through a Constant Head Apparatus while measuring permeability. Calculate the coefficient of permeability. · Volume of water passing through soil in time (t) = 100ml · Cross-sectional area of specimen = 500 mm2 · Thickness of specimen = 8 mm · Hydraulic head = 5 mm · Mean temperature of water during test = 20oc Time interval t = 2 minute
A falling head permeability test was run on a soil sample 9.60 cm in diameter and 10 cm long. The head at the start was 70 cm. The coefficient of permeability of the soil was found to be 5 x 10-6 cm/s. The diameter of the standpipe was 1 cm. What is the rate of flow at the start of the test? Select the correct response: 6.08 cm/hr 11.73 cm/hr 15.83 cm3/hr 9.12 cm/hr
