Question
The linear correlation coefficient is
r=
​(Round to three decimal places as​ needed.)
 
Determine the null and alternative hypotheses.
 
H0​:ρ __    ___
 
H1​:ρ ____   ____
(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.
