Consider a 90% confidence interval for μ. Assume Ï is not known. For which sample size, n=10 or n=20, is the critical value t(small c at bottom by t) larger? true n=20 would give a larger critical value t(with a small c at bottom by t)
false n=20 would not give a larger critical value t(with a small c at bottom by t)
true or false?

i hope this helps

step-by-step explanation:

it is the one with the most keychains.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
