Answer:
Step-by-step explanation:
What ever one you think is better.
Answer:
Examine the mathematical expression you're working on. For example, suppose you're given 5x + 3. There are two terms here, 5x and 3. Look for the variable. In this case, x is the variable. In your case its c
Find the numerical coefficient of x. Remember to look for the number before the variable. In this case, 5 is the numerical coefficient. The term 3 is a constant and is separated from the variable by a plus sign.
Keep an eye out for negative coefficients. For example, suppose you're given the statement -y + 7 + 98. You would first identify the variable, y.
Look for the numerical coefficient of y. In this case, a "1" is implied before the variable, but it's negative in this instance. Therefore, the coefficient of y is negative 1.
Answer:
Sample size, n = 543
Step-by-step explanation:
We are given the following in the question:
Margin of error = 5%
Confidence interval:

Margin of error =

Since no particular proportion is given, we take


Putting values, we get,

Thus, the sample size must be 543 so the sample proportion is will not differ by 5%
