QUESTION 25 If the researchers are hypothesizing that the amount of time that individuals held their hand in the bucket of ice water was related to working memory task score such that t longer someone held their hand in the ice water the lower their working memory task score would be. What is the Alternative hypothesis (H1)? The length of time that someone holds their hand under the water will change their working memory score. The length of time that someone holds their hand under the water is not related to their working memory score. The longer someone holds their hand in the water the higher their Working memory score will be. The longer someone holds their hand in the water the lower their Working memory score will be. QUESTION 26 If the researchers are hypothesizing that the amount of time that individuals held their hand in the bucket of ice water was related to working memory task score such that t longer someone held their hand in the ice water the lower their working memory task score would be. What is the Null Hypothesis (HO)? Decrease time in the water is related to lower working memory scores Increase time in the water is related to lower working memory scores Increase time in the water is not related to lower working memory scores Decreased time in the water is not related to lower working memory scores

Explanation / Answer

25. We are testing to check if increase in length of time will decrease the lower working memory scores, so

Answer: The longer someone holds their hand in the water the lower their working memory score will be.

26. Null hypothesis always holds the equality condition, so

Answer: Increase time in the water is not related to lower working memory scores.
