Histogram Exercise

 The simulated machine fills vials with liquid. You can set the required fill by rotating the dial (left click on the scale and rotate it whilst holding the left button down). There is variation in the process and the actual amount of liquid varies from vial to vial. I've collected a sample of 50 fill values for you. Create a histogram using the values, or if you prefer collect your own values.
