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

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

df denote degree of freedom and its value is

Here in question information about eleven different video games is given

so, here

We know that for calculation of degree of freedom we need sample size and df is always one less than sample size.

Therefore, degree of freedom =

So, the value of degree of freedom that is df is

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
