Answer:
The margin of error for the 90% confidence interval is of 0.038.
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 zscore that has a pvalue of .
The margin of error is:
To this end we have obtained a random sample of 400 fruit flies. We find that 280 of the flies in the sample possess the gene.
This means that
90% confidence level
So , z is the value of Z that has a pvalue of , so .
Give the margin of error for the 90% confidence interval.
The margin of error for the 90% confidence interval is of 0.038.
Answer:
<em>"Use the distance formula to find the length of each side, and then add the lengths".</em>
Step-by-step explanation:
By definition the perimeter of a quadrilateral is the sum of the length of its sides.
Therefore the first thing we should find is the length of the sides of the quadrilateral
If we have the vertices A, B, C and D of the quadrilateral then the distance between two of its vertices is the length of one of its sides.
For example, the distance between vertex A and vertex B is the length of the AB side. Then, using the formula of the distance between two points, we find the length of its sides and add them together.
Then the correct answer is: <em>"Use the distance formula to find the length of each side, and then add the lengths".</em>
