Question

Make a chart of the four possible correct and incorrect decisions in a hypothesis test. Then, answer the additional multiple choice question. Make a chart of the four possible correct and incorrect decisions in a hypothesis test. A child psychologist conducts a study to test whether infants born prematurely begin to walk earlier than do infants in general. Which of the following scenarios represents a Type I error? A) The psychologist concludes that premature infants do walk earlier than infants in general when the true situation is that they actually do not. B) The psychologist concludes that premature infants do walk earlier than infants in general when the true situation is that they actually do. C) The psychologist concludes that premature infants do not walk earlier than infants in general when the true situation is that they actually do. D) The psychologist concludes that premature infants do not walk earlier than infants in general when the true situation is that they actually do not.

Explanation / Answer

From the above chart type I error is nothing but the situation which support the research hypothesis but in real the null Hypothesis (H0) is true.

From the above question let's write the claim of the researcher

Claim: The infants born prematurely begin to walk earlier than do infants in general.

Here the situation (that is sample values) support this claim but in real it is not true then we say that Type I error is occur.

So correct option is A) The psychologist concludes that premature infants do walk earlier than infants in general when the true situation is that they actually do not.
