Answer:
Step-by-step explanation:
According to the desired test, the hypothesis are given by:
D) H0: μ=210
Ha: μ ≠ 210
At the null hypothesis, it is <u>tested if the population mean is of 210 lbs</u>, that is:
At the alternative hypothesis, it is <u>tested if the population mean differs from 210 lbs</u>, that is:
Hence, the correct option is:
D) H0: μ=210
Ha: μ ≠ 210

U can use elimination and multiply all the terms in the top expression to get 3x-3y = -4, or 4x = -4, so x = -1. plug it in to find y if needed
Answer:
<h3>The answer is ( 4 , - 2)</h3>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(2,-5); B(6,1)
So we have
We have the final answer as
<h3>( 4 , - 2)</h3>
