Given the linear correlation coefficient r and the sample size n, determine the critical value of r and use your finding to state whether or not the given represents a significant linear correlation. Use a significance level of 0.05. Given r=−0.568, n=25.

the answer should be a. snail

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.
