The df value for the t statistic for this study is 12.
To calculate the df value or degree of freedom we have to learn about test-statistic.
<h3>What is t statistics and how is it related to df(degree of freedom)?</h3>
In the field of statistics , T-statistic is the ratio of the estimated value of the perimeter to its standard error. Degree of freedom or df value denotes the number of data (from a sample) is used to calculate the estimate .
Importantly the degree of freedom is different from the sample space of an experiment.
The formula for calculating the df of a function is given by
df=N1+N2-2
So in the given question, N1=6 and N2=8
Substituting the values we get df=N1+N2-2=8+6-2=12 .
Therefore the value of the degree of freedom is 12.

Answer:
X = 13
Step-by-step explanation:
42 - X = 29
Subtract 42 from each side
42-42 - X = 29-42
-X = -13
Multiply each side by -1
X = 13
Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
200 Is 100 times as much as 2,
<em>200 / 2 = 100</em>
<em>and </em>
<em>100 x 2 = 200</em>
