Listed below are numbers of Internet users per 100 people and numbers of scientific award winners per 10 million people for different countries. Construct ascatterplot, find the value of the linear correlation coefficientr, and find theP-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

alphaequals=0.05

Construct a scatterplot. Choose the correct graph below.

The linear correlation coefficient r is ( round to three decimals)

Determine the null and alternative hypotheses.

The test statistic is ( Round to three decimals )

TheP-value is ( Round to three decimals )

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