Question
Does Hypnotism Relieve Pain?
The table shows the pain levels of patients before and after hypnotism. Pain level is measured on a cm scale. Assume that the two samples are randomly selected. At the 0.05 significance level, test the claim that the
(Be sure to subtract in the same direction).

Transcribed Image Text:Based on the hypotheses, find the following:
- Test Statistic = 5.000 (Round to three decimal places.)
- Critical value(s) = 1.895 (Round to three decimal places.)
- p-value = __________ (Round to four decimal places.)
Instructions:
Shade the sampling distribution curve with the correct critical value(s) and shade the critical regions. The arrows can only be dragged to t-scores that are accurate to 1 place after the decimal point (these values correspond to the tick marks on the horizontal axis). Select from the dropdown menu to shade to the left, to the right, between, or left and right of the t-score(s).
- **Shade:** Left of a value ☐. Click and drag the arrows to adjust the values.
Graph Description:
The graph displays a normal distribution curve centered at zero, representing a t-distribution. The horizontal axis is marked with tick marks ranging from -4 to 4. A critical region is shaded in blue on the left side of the curve starting around -1.5.
- **Decision:** Select an answer ☐.
- **Conclusion:** Select an answer ☐ the claim that the mean difference is less after hypnotism.

Transcribed Image Text:The image contains a table and a section for hypothesis testing related to measurements (in centimeters) before and after a certain event or treatment. Here is the transcription:
**Table: Measurement Differences**
| Before (cm) | After (cm) | Difference (cm) |
|-------------|------------|-----------------|
| 9 | 9 | 0 |
| 10.7 | 6.7 | 4 |
| 10.9 | 9.9 | 1 |
| 9.9 | 5.9 | 4 |
| 6.6 | 3.6 | 3 |
| 7.5 | 4.5 | 3 |
| 6.8 | 3.8 | 3 |
| 10.2 | 8.2 | 2 |
**Hypothesis Testing Section**
- **What are the correct hypotheses? (Select the correct symbols and values.):**
- \( H_0: \mu(d) \geq 0 \)
- \( H_1: \mu(d) < 0 \)
- **Original Claim = \( H_1 \).**
**Degrees of Freedom**
- **\( df = 7 \)**
The table lists paired data for measurements taken before and after an event for eight subjects. The third column depicts the differences calculated by subtracting the "After" measurement from the "Before" measurement. The hypothesis testing section involves setting a null hypothesis (\( H_0 \)) and an alternative hypothesis (\( H_1 \)) for the differences in these measurements. The original claim is associated with the alternative hypothesis. The degrees of freedom for the test is 7.
