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)
This would be written as 4-6x=40, then you subtract 4 from both sides to get -6x=36 which simplifies to x=-6.

W-1/4= 3/7
W-1/4+1/4= 3/7+1/4
find the common denominator for the fractions
common denominator is 28
Multiply by 4 , top and bottom for 3/7
Multiply by 7 , top and bottom for 1/4
W= 12/28+7/28
W= 19/28
Answer is W= 19/28
-645 you can't simplify any further
Answer:
3/-5
Step-by-step explanation:
Rise over Run is what Slope is. So basically we look at it and go how do we get from -6 to -3? Well you add 3, so thats your top number. We look at the bottom of the fractions now. We use the same thought process. How do you get from 14 to 9? Subtract 5. So our slope is 3/-5. Hope this helps
