Show your workRecently you’ve noticed that your kitchen blender (brand YZ) is not blending food as well any more. You have decided to invest in a new blender. Before you make a decision on which model to purchase you borrow three different brands of blenders AB CD and EF from friends and family and test them for yourself. Formulate a testable hypothesis. (5 points) Design an experiment to test your hypothesis (5 points). Be specific in your experimental design and include your controls. (5 points) Predict the experimental results that would support your hypothesis.
