[填空题]
The following table shows values of exim7y: (lwa+ ky(/uf lnx and lnyi:p o)f fe9ym5.
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 $p \neq 0$ and $q \neq 0$, $q \neq 1$ . ≈
3. Expressing ln y in terms of ln x , find the value of p and the value of q . p ≈ q ≈
