Answer: 0.9444
Step-by-step explanation:
Given: The proportion of politicians are lawyers : <em>p </em>=0.56
Sample size : n = 564
Let q be th sample proportion.
The probability that the proportion of politicians who are lawyers will differ from the total politicians proportion by greater than 4% will be :-
Hence, the required probability = 0.9444
Note that the first function is f(x) = 4 for x less than 2 and for the second function f(x) = -1 for x greater than or equal to 2
So the limit as x approaches two from the left is 4 and the limit as x approaches 2 from the right is -1.
so looks like you would need the third choice: 4; -1
Multiplication and division are inverse of each other. If you want to divide something by 2, you could also multiply it by .5 or (1/2). If you want to multiply something by 4, you could also divide it by (1/4) etc.
