To analyze:
An experimental design to test whether probiotic drinks can help with "slow intestinal transit time"and help "prevent cold and flu".
Introduction:
The Dannon company claims that its Activia yogurt helps with "slow intestinal transit time" and DanActive dairy drink helps "prevent cold and flu". Therefore, these claims need to be tested experimentally.
Since two products are being tested for their claims, two experiments need to be conducted. In each experiment, the participants receiving the product must be divided into two groups, with one receiving the product and the other receiving an inert substitute (that has no effect, but looks and tastes the same as the product). The experiments must be double-blind (the participants and the health professional giving these products do not know which participants are consuming the product and which participants are consuming the inert substitute).
The steps to test Activia yogurt consist of the following:
The steps to test DanActive dairy drink consist of the following:
By conducting double-blind experiments, using control and experiment groups, and critically testing whether the claims of Dannon company are true, the claims about their products Activia yogurt drink and DanActive dairy drink can be verified.
