Answer:
A = (2,1)
B = (4,2)
C = (5,3)
D = (6,6)
E = (4,6)
F = (3,4)
G = (1,6)
H = (6,0)
I = ( 0, 4)
Step-by-step explanation:
tips:
the format for coordinates is (x,y)
the horizontal line is the x axis, so you plot which number of x it lands on, like how A is on the second mark on the x axis.
The vertical line is the y axis, so you plot which number of y it lands onn like how A is on the first mark

Answer:
[ 0.4964, 0.5836 ]
Step-by-step explanation:
Data provided in the question:
Total sample size = 500
person voting for smith = 270
thus,
P( person voting for smith ), p =
= 0.54
Confidence level = 95%
now,
standard error, SE = 
or
SE = 
or
SE = 0.0223
now,
Confidence interval = p ± ( z × SE )
here,
z value for 95% confidence interval is 1.96
Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]
= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]
= [ 0.4964, 0.5836 ]
