Question

From 1996 to 2012, 84% of non-teacher workers were employed in private schools. If a random sample of 200 teachers in the years 1996-2012 was selected, what is the probability that between 78% and 86% were public school teachers?

Answer List

A.	0.2147
B.	y’ = -3x + 1.5
C.	2.571
D.	There is no significant correlation between the variables, therefore we should not determine the regression equation.
E.	y’ = 1.5x - 3
F.	0.0416
G.	2.72
H.	1.725
I.	0.7853
J.	0.2305
K.	r = 0 .773, looking at the graph and the correlation coefficient, there appears to be no correlation.
L.	2.447
M.	2.015
N.	0.7695
O.	r = 0 .773, looking at the graph and the correlation coefficient, it appears to be positive linear.
P.	y’ = 0.398x + 5.45
