Twenty different video games showing drug use were observed. The duration times of drug use ​(in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 93 ​sec, what does df​ denote, and what is its​ value?

Respuesta :

Answer:

19

Step-by-step explanation:

Here df denote the degree of freedom

The degree of freedom are the value which are free to vary

The degree of freedom can be calculated by subtracting one from the total sample space

Here total sample space that is n is given as 19

So degree of freedom that df =20-1 =19

So for the given question the degree of freedom will be 19
