The manufacturer of a soft-drink brand is considering making changes to its formula and is conducting a taste test to see if the original or the new formula is preferred. The names of 100 potential customers are numbered from 00–99, and a table of random digits is used to select 50 subjects. The subjects are served both formulas of soft drink and asked to choose which they prefer. Which of the following represents how this experiment could be made blind?

A) Serve the original formula in its current can and the new formula in a special cup.
B) Test administrators use identical cups, and mark the “A” or “B” on the bottom of each cup to identify the formula.
C) Serve in identical cups, one labeled “original” and the other labeled “new.”
D) Blindfold the participants and tell them which formula they are tasting.

Step-by-step explanation:In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80

The amount of discount during the weekend = (1.20 - 0.80) dollars

                                                                      = 0.40 dollars

So the amount of discount given during the weekend is $0.40

Now we need to find the percentage of discount given during the weekend.

Then

Percentage of discount during the weekend = (0.40/1.20) * 100

                                                                      = 0.33 * 100

                                                                      = 33

Then the percentage of discount given is 33%.
