Problem 2
Textbook Question
Textbook QuestionWhich of the following is an example of inductive reasoning? a. All cows eat grass; b. My cow eats grass and my neighbor's cow eats grass; therefore, all cows probably eat grass; c. If all cows eat grass, when I examine a random sample of all the cows in Minnesota, I will find that all of them eat grass; d. Cows may or may not eat grass, depending on the type of farm where they live
Verified step by step guidance
1
Identify the nature of inductive reasoning: Inductive reasoning involves making generalizations based on specific observations or experiences.
Analyze option a: This statement presents a general fact without showing the process of deriving the conclusion from specific observations.
Analyze option b: This option shows a process where a general conclusion ('all cows probably eat grass') is derived from specific observations ('My cow eats grass and my neighbor's cow eats grass').
Analyze option c: This statement sets up a hypothesis testing scenario, which is more aligned with deductive reasoning, where a general statement is tested with specific instances.
Analyze option d: This statement presents a possibility but does not derive a general conclusion from specific observations, hence it is not an example of inductive reasoning.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Inductive Reasoning
Inductive reasoning involves making generalizations based on specific observations or examples. It starts with specific instances and formulates broader conclusions that may not be universally true but are likely based on the evidence at hand. For example, observing that a few cows eat grass and concluding that all cows probably eat grass is an inductive leap.

Deductive Reasoning
Deductive reasoning is the process of drawing specific conclusions from general principles or premises. It begins with a general statement or hypothesis and examines the possibilities to reach a specific, logical conclusion. An example would be stating that if all cows eat grass, then examining a sample of cows should confirm that they all eat grass, which is a deductive approach.

The Human Population Example 1
Sample and Generalization
In statistics and reasoning, a sample refers to a subset of a population used to make inferences about the whole. Generalization occurs when conclusions drawn from a sample are applied to the entire population. The effectiveness of this process depends on the representativeness of the sample; if the sample is biased, the generalization may be flawed.
