Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
The answer is true, because there is only one number that can be squared to twelve.
Because 1 pound=16 ounces, they sold 7.5 pounds of the cherries. 201.5 pounds of cherries are left. Or 402 8 ounce bags
Step-by-step explanation:
Q1
7x people=14x^2/15
1 person= (14x^2/15)÷7x
// =(7x^2/15)÷x
Each person will recieve= (7x^2/15)÷x
