Answer:
Null hypothesis:
Alternative hypothesis:
The statistic to check the hypothesis is given by:
And is distributed with n-2 degreed of freedom. df=n-2[/tex]
For this case we got a significant result that means that the real correlation coefficient is different from 0 . And for this case the best interpretation would be:
This result indicates that earning more money influences people to recycle more than people who earn less money
Step-by-step explanation:
The correlation coeffcient is given by this formula:
For this case we know that this value of r is positive and represent a string correlation between income level and the number of containers of recycling
In order to test the hypothesis if the correlation coefficient it's significant we have the following hypothesis:
Null hypothesis:
Alternative hypothesis:
The statistic to check the hypothesis is given by:
And is distributed with n-2 degreed of freedom. df=n-2[/tex]
For this case we got a significant result that means that the real correlation coefficient is different from 0 . And for this case the best interpretation would be:
This result indicates that earning more money influences people to recycle more than people who earn less money
