A statistics graduate student conducted an experiment about graduate students who lived on campus. After taking a simple random
1 answer:
Answer:
She calculated a standard error of 0.048.
Step-by-step explanation:
A proportion p is the number of desired outcomes divided by the number of total outcomes.
The standard error of a proportion is given by:
In which n is the size of the sample.
In this problem, we have that:
Desired outcomes:
12 students living on campus
Total outcomes:
All the 65 students
Proportion:
Standard error of the proportion:

The perimeter of the kite is (10 + 2√53) units if the kite and the coordinates of the kite are point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).
<h3>What is quadrilateral?</h3>It is defined as the four-sided polygon in geometry having four edges and four corners. Kite is quadrilateral, in which. Two pairs of congruent sides, and it has one pair of opposite congruent angles.
The figure is missing.
On a coordinate plane, kite WXYZ is shown (please refer to the picture)
We have a kite and the coordinates of the kite are:
Point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).
Using the distance formula we can find the distance between coordinates:
Distance between W and X:
WX = 5 units
Similarly, distance between X and Y:
XY = √53 units
YZ = √53 units
ZW = 5 units
Perimeter = sum of the all sides
Perimeter = 5 + √53 + √53 + 5
Perimeter = (10 + 2√53) units
Thus, the perimeter of the kite is (10 + 2√53) units if the kite and the coordinates of the kite are point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).
