Question
The image displays a table comparing the number of words spoken per day by male and female twins of opposite gender. The study aims to determine if females speak more words than males among these twins, using a 0.10 significance level.

**Table Details:**

|         | Twin 1  | Twin 2  | Twin 3  | Twin 4  | Twin 5  | Twin 6  | Twin 7  |
|---------|---------|---------|---------|---------|---------|---------|---------|
| Male    | 15684   | 26429   | 14111   | 7771    | 18876   | 15477   | 14069   |
| Female  | 24624   | 23397   | 18338   | 17791   | 16964   | 16937   | 16255   |
| Difference (F-M)| 8940    | -3032   | 4227    | 10020   | -1912   | 1460    | 2186    |

**Key Statistics:**

- \( \bar{d} = 3127 \)
- \( s_d = 4991.72 \)

This analysis looks at the difference in the average number of words spoken by females and males and conducts a statistical test to verify if the observed differences are significant at the 0.10 level.
