Get a calculator, Multiply the 8 by the 3.4. You get 27.2. Now divide that by half. You get (C is the answer)
The formula for the area of a triangle is
Your answer is going to be Letter B
Answer:
n≅376
So sample size is 376.
Step-by-step explanation:
The formula we are going to use is:
where:
n is the sample size
p is the probability of favor
q is the probability of not in favor
E is the Margin of error
z is the distribution
α=1-0.98=0.02
α/2=0.01
From cumulative standard Normal Distribution
p is taken 0.5 for least biased estimate, q=1-p=0.5
n≅376
So sample size is 376
