Step-by-step explanation:
Hello,
In a Venn 's diagram: A={Custumer edu},B={french}, U=the class.
#(A\B)=22-2=20
#(B\A)=20-2=18
#(A∩B)=2
#U=80
p=(20+2+18)/80=20/40=1/2
Answer C (11/40+1/4-1/10=20/40=1/2)

Answer: n = 2401
Step-by-step explanation:
Given;
Confidence level = 2% - 99%
n = ? ( which is the sample size is unknown ).
Solution:
Where;
n = [z/E]^2*pq
Since no known value for ( p ) estimate is given, the "least biased" estimate is p = 1/2
Substituting the given data into the formula.
n = [1.96/0.02]^2(1/2)(1/2)
n = 2401
