Question 2 options a 45611 3051 b 79 11 c 79 0846 d 7

Question 2 options:

	a) = 45.611, = 3.051
	b) = 79, = 11
	c) = 79, = 0.846
	d) = 79, = 3.051

Solution

Note that by central limit theorem,

u(X) = u = 79

and

sigma(X) = sigma = 11/sqrt(13) = 3.050851079

Thus,

OPTION D: u(X) = 79, sigma(X) = 3.051 [ANSWER, D]
