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

80.3

78.2

56.4

67.6

77.7

38.6

Award Winners

Construct a scatterplot.

The linear correlation coefficient r is. ?(Round to three decimal places as? needed.)

Determine the null and alternative hypotheses. ?(Type integers or decimals. Do not? round.)

The test statistic is ?(Round to two decimal places as? needed.)

The? P-value is ?(Round to three decimal places as? needed.)

Because the? P-value of the linear correlation coefficient is (greater than, less than, equal to) the significance? level, there (is, is not) sufficient evidence to support the claim that there is a linear correlation between Internet users and scientific award winners.
