Transcribed Image Text: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 a = 0.05.

The linear correlation coefficient is r= 0.777
(Round to three decimal places as needed.)
Determine the null and alternative hypotheses.
Ho: P
H1: P
(Type integers or decimals. Do not round.)
The test statistic is t=
(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
the significance level, there
sufficient evidence to support the claim that there is a linear correlation between Internet users and scientific award winners.
