Answer:
Hypothesis testing of ' significance of difference between means'
Step-by-step explanation:
Study conducted to tests whether oxygen level prior SAT score improves test score. This can be done through - Hypothesis testing of ' significance of difference between means'.
Where x1 & x2 represent mean values of SAT test score before (or without) & after (or with) oxygen.
Null hypothesis [H0] = x1 = x2 , Alternate Hypothesis [H1] : x1 < x2

C
Step-by-step explanation:
Substitute n = 8 into the explicit rule
= - 
× 
= - 
×
= - 
= - 625 → C
Answer:
3e = k
2a - 6 = k
k = 18
we can plug in k first for each equation
3e = 18
e = 6
2a - 6 = 18
a = 12
k = 18
e = 6
a = 12
