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

Answer: He can mow 4 lawns before he needs to buy more gasoline.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Gallons of gasoline available: 2/3
</em>
- <em>Gallons of gasoline used for mow a lawn: 1/6
</em>
So, to find the number of lawn that he can mow, we have to divide the gasoline available (2/3) by the amount used for mow a single lawn (1/6)
Mathematically speaking:
2/3 ÷1/6 = (2x6) / (3x1) = 12/3=4
He can mow 4 lawns before he needs to buy more gasoline.
