A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion 
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value: 
Thus, the Margin of Error E = 




the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:

= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)
Short answer D <<<<
Dilation means you go from one diagram to another.
which direction (the figure increases or the figure decreases in size) is described by the scale factor.
In this question the scale factor is greater than 1. The figure is getting bigger.
so radius * scale factor = 2 * 4 = 8 is the answer.
If the question save dilated by a scale factor of 1/4 then the answer would have been 2 * 1/4 = 2/4 = 1/2
