Answer:
n = 2000
p - population proportion
%
Step-by-step explanation:
From the question we are told that
The sample size is
The proportion of the population for chocolate pie is
The margin of error is %
Now in the question we are asked to provide the meaning of
Now is the sample proportion of the population that those chocolate pie as favorite pie of which is given from the question as 0.11
Now
is the sample proportion of the population that choose other pies apart from chocolate pie as their favorite and it is evaluated as
n is the sample size which is given as n = 2000
E is the margin of error which given as %
p is the population proportion
Given that the confidence level is 95 % then the level of significance is mathematically evaluated as
%
5%
∠AXY=∠XBC=55°(corresponding angles)
XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°
The sum of all the angles in a triangle is 180°⇒
55°+55°+∠BXC=180°
∠BXC=70°
