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
V the significance level, there
sufficient evidence to support the claim that there is a linear correlation between Internet users and scientific award winners.
