The accompanying table lists the 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.

Internet users per 100 data, Award winners per 10 million data:
78.2, 5.4
83.0, 23.5
82.0, 8.7
40.1, 0.5
79.7, 5.0
38.9, 0.2
90.6, 23.8
93.7, 8.3
80.7, 10.4
84.3, 11.2
52.3, 3.2
81.2, 13.2
58.1, 2.4
76.4, 1.3
95.4, 10.8
97.5, 24.8
66.4, 2.0
54.7, 2.8
69.9, 2.9
97.7, 30.6
87.5, 31.7
83.6, 19.4
82.2, 9.9

What was your purpose in posting this? Do you just want someone to do your homework for you?

The problem asks you to construct a "scatter plot". Do you know what a "scatter plot" is? Do you know what a "linear correlation coefficient​" and "P-value" are?
