Construct a Scatterplot and Identify the Mathematical Model That Best $\mathrm { R } ^ { 2 }$

question 25

Multiple Choice

Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used
only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use
a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several
models and compare the values of $\mathrm { R } ^ { 2 }$
- $\begin{array}{c|cccccc}x & 1 & 2 & 3 & 4 & 5 & 6 \\\hline y & 9 & 13 & 25 & 27 & 31 & 46\end{array}$

• A) \(y = 3.14 + 6.59 x\)
• B) \(y = 1.07 + 6.89 x\)
• C) \(\mathrm { y } = 8.34 \mathrm { x } ^ { 0.88 }\)
• D) \(y = 4.87 + 18.5 \ln x\)
