Answer:
Step-by-step explanation:
As sample size increase the variability of the estimate of the proportion would decreases ( reduces)
The formula of variance of the estimator of the proportion is as
Since the denominator of the formula of the variance of sample proportion is n
so as n increase the variance of it decrease.
The center of the estimate of proportion would same
Because
which does not affect the value of n ( sample size).
Answer:
The correct answer is: Option H: 14.4 units
Step-by-step explanation:
CD is a line segment and let M be the mid-point of the line segment.
As we know that a mid-point divides the line in two equal parts, this means that the length of line segment will be the double of distance between one end and mid-point
Given
C( 2,-1) => (x1,y1)
M(8,3) => (x2,y2)
The distance formula is given by:
Putting the values
We know that
Hence,
The correct answer is: Option H: 14.4 units
