Question

a food scientist wants to know if increasing the amount of lemon juice in a hummus recipe by 10% will increase the shelf life of the product, so he prepares 100 Badges of the recipe - 50 following the old recipe and 50 with extra lemon juice –and?checks each batch once per day to see how long it stays fresh. What type of data source is this?​

Answer 1

`\fbox{\begin{minipage}{10em}Option B-Experiment\end{minipage}}`

Explanation:

As described, the food scientist performs the research based on the actual data, without using a computer or any simulation devices.

=> The data source is not generated from a computer simulation.

=> Option A-Simulation is incorrect.

The food scientist intentionally prepares the research by conducting an experiment, in which 100 badges are used, 50 badges following the old recipe and 50 badges with extra lemon juice.

=> This is not a subjective process, but a purposely attempting to observe the amount of lemon juice in a specific manner.

=> This is not a survey.

=> Option C-Survey is incorrect.

=> Option B-Experiment is correct.

Hope this helps!
