Question

the measure height of a person can be termed as a quantitative observation. true false question 5 1 pts quantitative observations are not measurable. true false question 6 1 pts which of these two statements meets the criteria of a scientific hypothesis? a. acids turn red litmus paper blue. b. all life in the universe exists on earth. statement a statement b

Explanation:

• Quantitative observations involve numerical measurements. A person's height is measured in units like centimeters or inches, so it is a quantitative observation. Thus, the first statement is True.
• Quantitative observations are measurable by definition (they use numbers and units), so the second statement "Quantitative observations are not measurable" is False.
• A scientific hypothesis must be testable. Statement a is incorrect as acids turn blue litmus paper red (common scientific fact, but if we assume it's a testable claim in a hypothesis - testing context). Statement b "All life in the universe exists on Earth" is testable (by exploring other planets, space etc. for life). But if we consider the scientific fact that acids do not turn red litmus blue (bases do), but in terms of hypothesis criteria (testability), both could be considered. However, if we go by correct scientific knowledge and hypothesis validity (a is factually wrong as a general statement for acids, while b is a testable claim even if it may be disproven). But if we assume the question is more about testability (as a hypothesis doesn't have to be correct, just testable), both are testable. But if there's a mistake in statement a (acids - litmus relation), and statement b is a broader testable claim about life in the universe.

Answer:

First question: True
Second question: False
Third question: Statement B
