Answer:
The answer is below
Step-by-step explanation:
The procedure of selecting a sample is thus called, fulfilling two fundamental properties:
-All individuals in the population have the same probability of being elected.
-All samples of the same size are equally likely.
From a mathematical point of view, simple random sampling is performed assuming that the population has infinite elements. In practice, it is often the case that the populations to be considered have a very large number of elements, which can be compared to a situation with infinite elements.
Yes, it is possible to sample data instances using a distribution different from the uniform distribution.
In excel, do the following to obtain a sample dataset.
E.g. to create a 5 element sample from the standard normal distribution, place the formula = NORM.S.INV (RAND ()) in cell A1, highlight the range A1: A15 and press Ctrl-D.
Answer:
Step-by-step explanation:
Rule for the rotation of a point 180° about the origin is,
(x, y) → (-x, -y)
Therefore, images of the points after the rotation of 180° will be,
A(2, 6) → A'(-2, -6)
B(6, 7) → B'(-6, -7)
C(5, 3) → C'(-5, -3)
D(1, 2) → D'(-1, -2)
Now we can plot these points on the graph as attached.
