Question
## 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.

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

The table summarizes the data for the two groups:

- **n**: Number of participants in each group.
- **mean**: Mean satisfaction score for each group.
- **SS**: Sum of squares, a measure of variability within each group.

### Experiment Analysis

#### Question:
What is the \( t_{obs} \) in **EXPERIMENT 1**? (round to two decimals)

#### Answer Input:
[__________]

---

In this educational exercise, students are prompted to identify and calculate \( t_{obs} \) for a given experimental context, in this case, **EXPERIMENT 1**. The students are instructed to round their answer to two decimal places and enter it into the provided input field. 

- **Explanation of \( t_{obs} \)**:
  - The symbol \( t_{obs} \) typically denotes the observed value of the t-statistic from a t-test. This is a standard statistical method used to determine if there is a significant difference between the means of two groups.

- **Rounding Instructions**:
  - Ensure that the calculated \( t_{obs} \) is accurate to two decimal places before submission.
  
This question tests the student's understanding of statistical analysis and their ability to apply rounding rules to produce accurate and meaningful scientific results.
