Step-by-step explanation:

Xj + Xk/2 = Xm

7 + Xk/2 = 1

to get rid of the bracket, multiply all two sides by the denominator.

2(7 + Xk/2) = 1(2)

7 + Xk = 2

Xk = 2 - 7

Xk = -5

Yj + Yk/2 = Ym

2 + Yk/2 = -2

to get rid of the bracket, multiply all two sides by the denominator.

2(2 + Yk/2) = -2(2)

2 + Yk = -4

Yk = -4 - 2

Yk = -6

Therefore the coordinates of point K is (-5,-6)

Determine the sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a me
zaharov [31]

The sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of x =2. is A. -0.7.

Given:

Random number=10

mean of x=2

population=125

mean of p=2.7

Using this formula

Sampling error=x− μ

Where:

x= sample mean=2

μ=population mean=2.7

Let plug in the formula

Sampling error=2-2.7

Sampling error=-0.7

Inconclusion the sampling error is A.-0.7.
