Suppose you are the marketing manager of a juice company that sells a variety of fruit juices. After conducting a blind taste test, you find that consumers your juices too bland. Therefore, you decide to increase the sweetness of your juices. If the sweetness of juices can be scored from 0 to 100, then your original lemonade was a 40 and your original grape juice was a 90. During an initial test, you found that increasing the sweetness of the lemonade by exactly 5 points would make consumers find the new lemonade just a bit sweeter than the original lemonade. Answer the following three questions: (a) describe how to use the Ascending Method to identify the just noticeable difference of the lemonades, (b) use Weber's Law to calculate the constant for detecting juice sweetness differences, and (c) use Weber's Law to obtain the just noticeable difference for creating a new grape juice. For all calculations, show step-by step computations.
