Answer:
The F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.
Step-by-step explanation:
There are four treatments in the data given, i.e. k = 4.
Total number of observations, n = 12.
Note: degrees of freedom is denoted as df.
For treatment, the degrees of freedom = k-1 = 4-1 =3 df.
The total degrees of freedom = n-1 = 12-1 = 11 df.
The error in degrees of freedom = df (total) - df(treatment)
The error in degrees of freedom = 11 - 3 = 8 df
At α = 0.05 level,from the F table, the F-statistic with (3 , 8)df is 4.07.
Therefore, the F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.
Monomials are the expressions with one terms.
A.) 
Since, it has only one term. Therefore, it is a monomial.
B.) 
Since, it has two terms. Therefore, it is not a monomial.
C.) 
Since, it has only one term. Therefore, it is a monomial.
D.) 
Since, it has only one term. Therefore, it is a monomial.
E.) 
Since, it has only one term. Therefore, it is a monomial.
F.) 
Since, the variable is in the power. So it is not a monomial.
G.) 
Since, the power is not a integer. Therefore, it is not a monomial.
