The table below lists the average hand span, h centimeters, and typing speed, T words per minute, of seven people.
| Hand span (h) | 20 | 22 | 21 | 19 | 24 | 21 | 16 |
| Typing Speed (T) | 40 | 40 | 34 | 37 | 53 | 41 | 32 |
The relationship between the variables can be modeled by the regression equation T=ah+b
a) i) find the value of A and find the value of B
ii) Find the Pearson’s product-moment
b) interpret, in context, the value of r found in part (a)(ii).
A particular person is found to have a hand span of 21.5 cm.
c) Use the result from part (a)(i) to estimate their typing speed.
