Question

question 4
which hypothesis is the best testable hypothesis, correctly written?
if grass gets fertilized, then it will grow faster.
when my puppy wakes up, he is hungry.
if the earth moves out of its orbit, life will not survive.
question 5
researcher bias occurs when the researchers beliefs or expectations influence the research design or data collection process.
which example is of researcher bias in interpreting data?

Explanation:

A good testable hypothesis has a clear cause - and - effect relationship and can be practically investigated. The statement about grass fertilization can be tested by comparing fertilized and non - fertilized grass growth. The puppy statement is more of an observation without a clear testable variable. The earth - orbit statement is not testable as we cannot manipulate the earth's orbit. For researcher bias in data interpretation, it involves misinterpreting results based on pre - conceived notions.

Answer:

Question 4: If grass gets fertilized, then it will grow faster.
Question 5: (No options provided to answer this part fully. But conceptually, an example could be a researcher expecting a certain drug to be effective and misinterpreting data to support that belief even when the evidence is weak.)
