We can say that there is sufficient evidence that revenue and the number of downloads are linearly related.
What is the null hypothesis?
The null hypothesis is a common statistical theory that asserts that no statistical relationship or significance exists between two sets of observed data and measured phenomena based on a single observed variable.
Hypothesis:
[tex]H_0:\rho_1=0\\H_1:\rho\neq0[/tex]
Test statistic:
[tex]t=r\times\sqrt{\frac{n-2}{1-r^2} }\\\\ t=(0.8691)\times\sqrt{\frac{30-2}{(1-0.8691)^2} } \\\\t=9.2974[/tex]
D.F. = n - 2 = 28
P-value = P-value at t = 9.2974, ∝=0.05, 28 d.f. is
P-value = 0.000
Conclusion: Since. P-value < ∝=0.05, so we have to reject the null hypothesis.
Hence, we can say that there is sufficient evidence that revenue and the number of downloads are linearly related.
