Discuss how the concept of statistical independence underlies statistical hypothesis testing in general. based on statistical analysis, are we justified in asserting that two variables are statistically dependent? why or why not? explain why researchers typically focus on statistical independence rather than statistical dependence.

answer: the four apples you took away.

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
