Answer:
C. (n₁ + n₂ - 2) degrees of freedom
Step-by-step explanation:
The t-test for difference between two mean when variance are equal is:
where ,
= Mean of Sample 1
= Mean of Sample 2
s = standard deviation
n_1 = size of Sample 1
n_2 = size of Sample 2
and t is Student's t-test with (n₁ + n₂ - 2) degrees of freedom.
Let jae have x dollars. Thus, we can make the equation:-
x + 3x + 2*(3x) = 400
4x + 6x = 400
10x = 400
x = 40
So jae has $40 and
jaspar has 3x = 3* 40
= $120 dollars (answer
