The following table shows values of lnxc 7dmg*ejgh zkg kwxx45 q(/5* aa6yh7ds *3ui h n)vd,znd lny.



The relationship between ln x and ln y can be modelled by the regression equation ln y=a ln x+b .
1. Find the value of a and the value of b .a ≈    b ≈   
2. Use the regression equation to estimate the value of y when x=4.12 .

The relationship between x and y can be modelled using the formula $y=p{x}^q$ , where $p\ne 0$ and $q\ne 0$, $q\ne 1$ . ≈   
3. Expressing ln y in terms of ln x , find the value of p and the value of q . p ≈    q ≈
