Answer:
The degrees of freedom for this problem are 21
Step-by-step explanation:
Degrees of freedom:
When testing an hypothesis involving two samples, the number of degrees of freedom is given by:
![df = n_1 + n_2 - 2](https://tex.z-dn.net/?f=df%20%3D%20n_1%20%2B%20n_2%20-%202)
In which
is the size of the first sample and
is the sample of the second sample.
In this question:
Samples of 9 and 14, so ![n_1 = 9, n_2 = 14](https://tex.z-dn.net/?f=n_1%20%3D%209%2C%20n_2%20%3D%2014)
The degrees of freedom for this problem are
![df = n_1 + n_2 - 2](https://tex.z-dn.net/?f=df%20%3D%20n_1%20%2B%20n_2%20-%202)
![df = 9 + 14 - 2 = 21](https://tex.z-dn.net/?f=df%20%3D%209%20%2B%2014%20-%202%20%3D%2021)
The degrees of freedom for this problem are 21
