Answer: 601
Step-by-step explanation:
When the prior estimate of the population proportion is unavailable , then the formula to find the sample size is given by :-
, where E = margin of error
and z* = Critical z-value associated with the confidence level.
As per given , we have
The prior percentage of full-time college students who earn a bachelor's degree in four years or less is not given.
E= 0.04
We know that the critical value for 95% confidence level = z*= 1.960
Then , the required sample size is given by :-
Hence, the required sample size is 601.
Answer:
D. 10x - 20
Step-by-step explanation:
The perimeter is the sum of all the sides of the rectangle.
Set up your equation. Because the opposite sides of the rectangle are equal, you add them twice or multiply it by 2.
P = 2(2x - 8) + 2(3x - 2)
Now distribute the 2 across the parentheses.
P = 4x - 16 + 6x - 4
Combine the variables.
P = 10x - 16 - 4
Combine the constants.
P = 10x - 20
