Question:
We use the regression equation to predict a step length fromhuman height.
The regression equation is:
What the step length does the model predict for a human heightof 65 inches? What the step length is predicted for a human heightof 75 inches?
| Step length (inches) | Height (inches) |
| 25.6 | 65.4 |
| 26 | 66.2 |
| 26.3 | 67.6 |
| 26.6 | 66 |
| 27 | 70 |
| 27.3 | 72 |
| 27.5 | 70.3 |
| 28 | 69.4 |
| 28.4 | 69.8 |
| 29.1 | 70 |
| 29.3 | 70.4 |
| 29.5 | 71.4 |
| 29.7 | 70.5 |
| 29.8 | 69 |
| 30 | 73 |
| 30.5 | 74 |
| 31 | 73.2 |
| 31.5 | 72.5 |
Use technology and the given dataset to find and interpret a 95%confidence interval for the mean the step length of humans whoheight of 75 inches.
