I think the correct answer is linear
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
Two squares root. Because 3 * 3 = 9 and -3 * -3 = 9.
If your trying to solve for x it’s 40, x=40
2 times 1/2x =2x20
x=2x20
x=40
