where ,
= Standard deviation for sample 1.
= Size of sample 1.
= Standard deviation for sample 2.
= Size of sample 2.
Let the sample of Latino name is first and non -Latino is second.
As per given , we have


The standard error for the difference in means will be :

Answer:
it would cost $10.8 for 9 chicken wings.
Step-by-step explanation:
Cost of 22 chicken wings = $26.40
we have to find first, cost of 1 chicken wings
For that we divide both side by 22
cost of 22/22 chicken wings = $26.40/22 = 1.2
Thus, cost of 1 chicken wings = $1.2
to fins cost of 9 chicken wings
we multiply both sides by 9
cost of 1*9 chicken wings = $1.2*9
cost of 9 chicken wings = $10.8
Thus, it would cost $10.8 for 9 chicken wings.
I believe the answer is C.
