correlation r	0.875090493
R square	0.765783371
estimate of population slope	1.97160452
standard error of slope	0.110144462
Confidence interval
95% of samples slopes are within		1.984467455
standard errors of the population slope
you can be 95% confident the population slope is between
1.753026421
and
2.190182619
0 is not in the confidence interval so there is strong evidence of a relationship
Hypothesis testing
test stat of slope	17.90016939
two sided p-value for slope	1.18336E-32
To calculate the p-value H0:population slope =0 is assumed to be true
since the test is two sided H1 is H1:population slope 0
