Use the following for questions 20-25
Dental disease in domestic cats is commonly associated with the accumulation of plaque on the teeth. A cat food manufacturer is studying the accumulation of plaque on the teeth of cats from a certain population. The accumulation of plaque is assessed using a fluorescent light technique (FLT), where an evaluator reviews images of the cat's teeth and assigns an overall rating from 0 to 100, with lower values indicating less plaque.
The manufacturer conducted a study to answer the question: How large is the size of the difference in accumulation of plaque on the teeth of cats between a new dental treat and the existing dental treat? The manufacturer randomly assigned 70 cats from a cat sanctuary to receive one of the two dental treats, with 35 receiving the new treat and 35 receiving the existing treat. At the end of the study, an evaluator, who was not aware of each cat's assigned dental treat, determined the FLT rating for each cat.
I just needed help with this question below...
Can the findings of the study be generalized to all cats? Explain why or why not, based on the design of the study.

Answer:
We can not generalize the results for all cats because cats are not selected randomly, and an inadequate sample size (70) does not represent the wider population.
Step-by-step explanation
Generalization is an extension of result finding on a sample population to the large population. If the sample population is large, we can generalize the result for all cats.
In our research study, a treatment applies for only 70 cats from one sanctuary, which does not represent the proportion of population. It is too small to generalize the results for all cats.
So, the results are poor to generalize for all cats.
Sometimes, the cat receives the treatment, but does not show the response on a treatment or a late reply. A low response of a treatment can impact on generalizing the effect.
For generalizing the results, cats should be randomly selected from different sanctuaries, but in our research study, cats are neither selected randomly, nor the sanctuary is different, so we cannot generalize the results for all cats.
