Question

Eleven 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 95 ​sec, what does df​ denote, and what is its​ value? What does df​ denote

Answer 1

Answer:

10

Step-by-step explanation:

df denote degree of freedom

here in question it is given that eleven different video games showing

so here n=11

we know that for calculation of degree of freedom

we can calculate degree of freedom if the sample size n is given degree of freedom is 1 less than sample space

so degree of freedom = sample size -1 =11-1 =10

so the value of degree of freedom that is df is 10
