A researcher would like to determine whether regular doses of St. John's Wort have an effect on memory for college students. A group of 50 students is selected and each student is given a standardized memory test. Then each of the students takes a daily dose of St. John's Wort for 6 weeks. At the end of 6 weeks, the students are once again given a memory test. The researcher intends to compare the scores from the two tests whether there is any change in memory ability. - is the sample in the study. - is the population in the study.

step-by-step explanation:

i dont know

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.
