For the Data Below, Determine the Logarithmic Equation $$\hat { y } = a + b \ln x$$

For the data below, determine the logarithmic equation, $$\hat { y } = a + b \ln x$$ that best fits the data. Hint: Begin by replacing each x-value with ln x then use the usual methods to find the equation of the least squares regression
Line. $\begin{array}{c|ccccl}\mathrm{x} & 1.2 & 2.7 & 4.4 & 6.6 & 9.5 \\\hline \mathrm{y} & 1.6 & 4.7 & 8.9 & 9.5 & 12.0\end{array}$

A) $\hat { y } = 0.457 + 5.06 \ln x$
B) $\hat { y } = - 0.458 + 5.36 \ln x$
C) $\hat { y } = - 1.81 + 6.91 \ln \mathrm { x }$
D) $\hat { y } = 0.881 + 4.86 \ln \mathrm { x }$
