The missing digits is highlighted in bold form
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)
Answer:
B, 36 sandwiches
Step-by-step explanation:
120/100 is equal to 1.2. so 1% is 1.2. then multiply that by 30, and you get 36 sandwiches
-4/7 - 4/3
- 12/21 - 28/21 = -40/21
your answer is -1 19/21
hope this helps
taller, a 90% error??? I 'm not sure, but the first one I am sure.
