The text in the image reads:"The P-value is [______]."Below this is an instruction:"(Round to three decimal places as needed.)"This indicates a field for entering the P-value, with guidance to round the value to three decimal places. There are no graphs or diagrams included in this image. Listed below are numbers of Internet users per 100 people and numbers of scientific award winners per 10 million people for different countries. Construct a scatterplot, find the value of the linear correlation coefficient \( r \), and find the P-value of \( r \). Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Use a significance level of \( \alpha = 0.01 \).\[\begin{array}{|c|c|}\hline\text{Internet Users} & \text{Award Winners} \\\hline78.2 & 5.6 \\78.5 & 9.1 \\57.8 & 3.4 \\66.4 & 1.6 \\78.7 & 10.4 \\38.4 & 0.1 \\\hline\end{array}\]**Construct a scatterplot.
