Answer:
The population mean is a true measure of the central tendency of the distribution of Y whereas the sample average is an estimator of the population mean.
Step-by-step explanation:
Out of all the statements given the correct statement is:
The population mean is a true measure of the central tendency of the distribution of Y whereas the sample average is an estimator of the population mean.
A sample mean is calculated from a dataset that is sampled out of the entire population data. And this sample mean is used to estimate or predict the population mean
Step-by-step explanation:
Diameter = r × 2
Where r = 2m
D = 2×2 = 4m
C= (3.14) × 4
= 12.56

<span>-ends of diameter: (-17,-9) & (-19,-9)
-- The distance between the ends of the diameter is 2,
so the radius is 1.
-- The center of the circle is the midpoint of the diameter ... (-18, -9) .
<em> (x+18)² + (y+9)² = (1)²</em>
-ends of diameter: (-3,11) & (3,-13)</span>
<span>-- The distance between the ends of the diameter is √612,
so the radius is (1/2) √612 = √153 .
-- The center of the circle is the midpoint of the diameter ... (0, -1) .
<em> (x)² + (y+1)² = 153</em></span>
