Answer:
n is 192
Step-by-step explanation:
Given data
Cl = 95%
interval = 0.2
to find out
what value n
solution
we have interval = 0.2
so interval has width at most is 0.5 so
margin of error E = 0.2 /2 = 0.1
and we know Z value for 95% Cl is 1.96 from z table
so sample n = Z²/E² ( ( 1 - 0.5) 0.5 + ( 1 - 0.5) 0.5 )
n = 1.96²/0.1² ( ( 1 - 0.5) 0.5 + ( 1 - 0.5) 0.5 )
n = 192.08
so n is 192
Answer:
the answer is
Step-by-step explanation:
You have to find the common denominator in order to get the sum.
