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 = 0.05.

Internet Users       79.4      79.3      56.6      68.8      77.5      37.6

Award Winners       5.7        8.8       3.3        1.8       10.9       0.1

 

Construct a scatterplot. Choose the correct graph below.

The linear correlation coefficient is r = ___

(Round to three decimal places as needed.)
