### EXPERIMENT 1

When a romantic relationship goes bad, both people experience emotional pain regardless of who was the initiator of the breakup. You believe that if you hypnotize people and tell them positive things about the future while under hypnosis, it will lessen the pain of a breakup. You put an advertisement in the newspaper looking for people who have recently broken up. From the people that answered your ad, a random sample of 20 individuals was taken and they were put into two groups of n=10. Members in each group were newly broken up less than 10 days. One group is hypnotized each day for seven days and told positive things about the future. The other group watched YouTube videos each day on how to deal with a breakup. After seven days, you give the participants a post-breakup satisfaction questionnaire. Higher scores mean more satisfaction with their current situation of being broken up. The descriptive statistics are shown below. Use those descriptive statistics to answer the following questions.

#### Descriptive Statistics Table:

|              | Hypnotized | Video |
|--------------|------------|-------|
| **n**        | 10         | 10    |
| **Mean**     | 21.8       | 19.1  |
| **SS**       | 123.6      | 60.9  |

- **n** represents the number of participants in each group.
- **Mean** represents the average satisfaction score.
- **SS** represents the sum of squares, which is a measure of variability within each group.

#### Explanation of Descriptive Statistics:

- **Hypnotized Group:**
  - Number of participants (n): 10
  - Average satisfaction score (mean): 21.8
  - Sum of squares (SS): 123.6

- **Video Group:**
  - Number of participants (n): 10
  - Average satisfaction score (mean): 19.1
  - Sum of squares (SS): 60.9

These statistics indicate that, on average, participants who were hypnotized reported slightly higher satisfaction scores post-breakup compared to those who watched videos.

### Hypothesis Testing in Experiment 1

In **EXPERIMENT 1**, the significance level \(\alpha\) is set at 0.05, and the test being conducted is a two-tailed test. The objective is to determine the effect of hypnosis on the pain experienced from a breakup.

#### Question:
Given these parameters, what would you conclude regarding the effects of hypnosis on the pain of a breakup?

#### Options:
- ○ Fail to Reject \(H_0\)
- ○ Reject \(H_0\)
- ○ Reject \(H_1\)

**Note:** In hypothesis testing:
- \(H_0\) typically represents the null hypothesis, which suggests no effect or no difference.
- \(H_1\) represents the alternative hypothesis, which suggests there is an effect or difference. 

Two-tailed tests are used when we are interested in deviations in both directions (greater than or less than the hypothesized value). The significance level (\( \alpha = 0.05 \)) indicates that there is a 5% risk of concluding that a difference exists when there is no actual difference.
