Biology - Assignment Example The number of cups of coffee should also depend on how much the escort and the professor can wager. 4. I believe the cups should not be identical. Perhaps there should be 3 designs and 4 pieces each, so 12. Maybe the design can affect the result of the experiment. I believe one kind of design is glass, another is plastic and the other is ceramic, because the coffee or milk might taste different with different material of the cup. If possible, I would like to prepare some cold and some hot, because it is possible that temperature might also affect the taste of the coffee or milk. 5. The order that the cups should be presented must be random so the only way I could think of is by jumbling the arrangement of all 12 cups but the escort and professor should take note which cup has milk or coffee added first. After that, any random cup from the group of 12 cups can be given to the model until she finishes tasting everything. 6. I think if she has guessed at least 75% of the cups correctly (minimum of 9), then we can say that the hypothesis is true. If we decide only after 50%, then maybe it is not enough and maybe she is just a good guesser. 1. The hypothesis I chose was different because it was a practical hypothesis. According to Fisher, if we use a null hypothesis we can exclude the possibility that the order of the cups has an influence on the results. However, if we use another hypothesis, then there might be confusion. So it is better to say that the order of the cups and other factors have no effect on the ability of the model to distinguish whether coffee or milk was added first. 2. My answer was the same as Fisher’s. I thought that â€Å"if only two cups are given to the model, then she will be able to simply freely guess whether the first cup had milk added first or if it is the second one.† According to Fisher, if only 3 cups can be chosen, then complete success can be achieved by pure chance. 3. I said the
