Question
**Exploration of Chocolate Consumption and Happiness** Assume you are a psychologist studying the relationship between chocolate consumption and happiness. You ask 10 participants to rate how much chocolate (in ounces) they ate in the last week, and how happy they felt throughout the week on average, on a scale ranging from 1 (extremely unhappy) to 10 (extremely happy). You hypothesize that there is some relationship between chocolate consumption and happiness. Here are their scores: | Participant # | Chocolate eaten during week (oz) | Happiness rating | |---------------|---------------------------------|------------------| | 1 | 5 | 3 | | 2 | 6 | 9 | | 3 | 3 | 7 | | 4 | 7 | 6 | | 5 | 4 | 4 | | 6 | 6 | 8 | | 7 | 10 | 1 | | 8 | 2 | 5 | | 9 | 8 | 9 | | 10 | 9 | 7 | This data can be used to explore possible correlations between the amount of chocolate consumed and perceived happiness levels.

**Transcription for Educational Website:** --- With α = .01, complete step 4 of the hypothesis testing procedure. What decision should the researcher make regarding the relationship between the time spent throwing paint at a canvas and participants' positive mood scores? - O The researcher should retain H₀ and conclude that chocolate consumption is not significantly related to happiness. - O The researcher should reject H₀ and conclude that chocolate consumption is not significantly related to happiness. - O The researcher should reject H₀ and conclude that chocolate consumption is significantly related to happiness. - O The researcher should retain H₀ and conclude that chocolate consumption is significantly related to happiness. --- **Explanation:** In this task, the researcher is asked to determine the appropriate decision regarding the null hypothesis (H₀) based on the significance level (α) of 0.01. The text mistakenly mentions "chocolate consumption" when referring to the relationship between time spent in an activity and the resulting mood. The decision involves either retaining or rejecting the null hypothesis, which has implications for understanding the significance of the relationship studied.
