The average income in a state was $54000 per person per year. suppose the standard deviation is $27000 and the distribution is right-skewed. suppose we take a random sample of 100 residents of the state. complete parts (a) and (b) below. what value should we expect for the sample mean? why? the expected sample mean is $because the type a whole number.) b. what is the standard error for the sample mean? the standard error for the sample mean is (type an integer or a decimal. do not round.)

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

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.
