Answer: the margin of error is 0.02
Step-by-step explanation:
Confidence interval for population proportion is written as
Sample proportion ± margin of error
If the confidence interval for this population proportion is (0.52, 0.56.), it means that the lower boundary is 0.52 and the upper boundary is 0.56
Let x represent the sample proportion and y represent the margin of error. Therefore,
x - y = 0.52
x + y = 0.56
Subtracting the second equation from the first equation, it becomes
- 2y = - 0.04
y = - 0.04/-2
y = 0.02

Answer:
17%, or $25.50
Step-by-step explanation:
If Ricardo has already saved 83% of the money, then he needs to save 17% more, because 83% + 17% = 100%
So what you need to do to figure out the answer is to find out 17% of $150
You first have to convert 17% into decimal form which is 0.17.
Then, you multiply 0.17 × 150 = 25.5
Ricardo needs $25.50 to buy the skateboard.
Hope this helped.
