IgorC [24]

The conditions which must be met to use z procedures in a significance test about a population proportion include:

I. The population is greater than 10 times the sample size.

II. The probability of success multiplied by the sample size is greater than or equal to 10.

III. The probability of failure multiplied by the sample size is greater than or equal to 10.

<h3>What is Z procedure?</h3>

This is a statistical test done on data that follows a normal distribution and determines if the population means are different when the variances are known and the sample size is large.

The population must be greater than 10 times the sample size in this scenario with the other appropriate conditions being mentioned above.

Find the midpoint of the line segment joining points A and B A(2,-5); B(6,1)
Rzqust [24]

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

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(2,-5); B(6,1)

So we have

M = ( \frac{2 + 6}{2}   \: , \:  \frac{ - 5 + 1}{2} ) \\  = ( \frac{8}{2}  \: , \:  -  \frac{4}{2} )

We have the final answer as

<h3>( 4 , - 2)</h3>

Hope this helps you
