Transcribed Image Text:**Sitting Height Study Overview**
The sitting height of a person refers to the vertical distance from the sitting surface to the top of the head. The data provided below represent the sitting heights, measured in millimeters (mm), of randomly selected U.S. Army personnel. This was collected as part of a substantial, reputable study. The data are analyzed with a significance level of 0.05 to deduce insights.
**Table: Sitting Height Data**
| | Right-Handed | Left-Handed |
|--------|------------------------|------------------------|
| Female | 857, 879, 874, 785, 896| 871, 857, 886, 847, 813|
| Male | 944, 909, 903, 913, 947| 1001, 916, 1030, 915, 977|
- **Description:**
- The table shows the sitting heights categorized by handedness (Right-Handed and Left-Handed) and gender (Female and Male).
- For each category, individual data points represent the sitting height in millimeters of each participant.
**Analysis Task**
Using this data, analyze and conclude any significant differences in sitting heights based on handedness and gender, utilizing a 0.05 significance level for statistical testing.
