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:
4a) 135×11/5= 297 miles
b) 216/27= 8 gallons (27miles is the distance one gallon can go)
5) 4+3+4=11
4/11 × x=160
4x=1760
x= 440
6) $4.20/14= $0.3...cereal A
$3.90/12= $0.325...cereal B
Cereal A os the better buy
7) 4×30/3= 40 presents
Hope it's all correct :-)
Try using photomath its an app where u take a pic of the problem and I solves it for you and shows u the working
Answer:
i did it again i did i did not do did it
Y= 2x-3 i think, but i may be wrong
