As a pollster, you randomly called 845 voters to know their positions on a California State’s ballot proposition. Only 80% of the voters agreed to answer your questions. Of those who answered you, 386 voters favored the proposition. (a)[2] Explain why this situation should not be considered as the finite population case. (b)[2] Check if the sampling distribution of the sample proportion can be approximately Normal. (c)[3] Construct the 92% CI for the favor proportion π. Sketch the CI. State if π can be 0.52. (d)[3] Construct the 96% CI for the favor proportion π. Sketch the CI. State if π can be 0.55. Hint: Round off probabilities and values to 5 decimal places. Refer to some Excel value lookups: NORM.

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
