To find: The experimental units, explanatory variable, response variable and the treatments.
Explanation of Solution
Given:
Revolting fries Few individuals need to eat stained fries. Potatoes are kept refrigerated before being slice for fries to forestall ruining and protect flavor. Yet, quick handling of cold potatoes causes staining because of complex substance responses. The potatoes should in this way be brought to room temperature before handling. Scientists need to structure an examination in which testers will rate the shading and favor of fries arranged from a few gatherings of potatoes.
The experimental units are considered as the part of original population for which the researcher collects the information. Here, experimental units are the potatoes that are being used.
Explanatory variables are time of storage and slicing time till cooking.
Treatments are imposed on subjects to get their opinions by an experiment. Here, treatments are:
- Fresh and cooked immediately.
- Fresh and cooked after one hour.
- Stored and cooked later.
- Kept in refrigerator and cooked immediately.
- Kept in room temperature and cooked later.
- Kept in refrigerator and cooked in an hour.
A response variable is a variable that is used to measure the outcome. Here, flavor and color rating are the response variables.
