Answer:
Option A.
Step-by-step explanation:
In an experiment a mouse took the mean time to find its way through a maze = 18 seconds.
So the mean time μ = 18
So null hypothesis says,
H₀ : μ = 18
Then a researcher thought that the mice can complete the maze faster than the time taken earlier.
So he thinks mean time taken by 10 mice will be less than 18 seconds.
Or μ < 18
Alternate hypothesis says will be
Hₐ : μ < 18
Therefore, null hypothesis and alternate hypothesis will be
H₀ : μ = 18
Hₐ : μ < 18
Option A. will be the answer.
Answer:
I decided to take a picture since it was easier for me that way. Hope you don't mind. Oh and if my number line isn't clear, the answer is the first number line
5.29 meters hope that helps.
Okay. All we have to do is look at this graph and see what points out of those answer choices show up. (-2, 4) is on the line (actually where the line intersects) but what about the others? (4, -2) and (4, 3) are not connected with any of the lines, so C and D are eliminated. (3, 4) is on the line, but that's not where both lines intersect. Intersecting lines at a point shows that the point is the solution, in this case (-2, 4) is the solution to this system of equation. The answer is A: (-2, 4).
It’s C because I got an A on that quiz and it was pretty hard
