The manager of an automobile dealership is considering a new bonus plan designed to increase sales volume. Currently, the mean s

Tcecarenko [31]

Answer:

The most appropriate null hypothesis for this situation is

$H_0$ : The mean sales volume is equal to 24.

the most appropriate alternative hypothesis for this situation is

$H_a$ : The mean sales volume is greater than 24.

Step-by-step explanation:

<em>The null hypothesis $H_0$ is the fact that is established and consider as true fact. </em>

Since the established mean sales volume is 24 automobiles per month this should be considered as the null hypothesis.

So, the most appropriate null hypothesis for this situation is

$H_0$ : The mean sales volume is equal to 24

<em>The alternative hypothesis is a fact that intends to reject or refute the null by collecting data that could contradict it. </em>

In this case, since the manager wants to conduct a research study to see whether the new bonus plan increases sales volume, he wants to see if the data collected after the new bonus plan can show that the new average is greater than the established one.

So, the most appropriate alternative hypothesis for this situation is

$H_a$ : The mean sales volume is greater than 24.

To try and prove that $H_a$ shows enough evidence as to assure the new plan actually increases sales volume, he must fix a significance level $\alpha$ , for example 0.1 or 0.05, which gives the probability that $H_a$ is not wrong in case that it rejects $H_0$ .

This confidence level defines an $\alpha$ -score $z_\alpha$ which is a point such that the area under the normal curve N(0;1) to the right of $z_\alpha$ is less than $\alpha$ .

<em>In this case we considered the right side because you want to see the new average is greater than the established one. </em>

<em> If the z-score obtained through the sample is greater than $z_\alpha$ then you can say the new bonus actually increases sales. </em>

<em>If the z-score obtained through the sample is less than or equals to $z_\alpha$ then you do not have enough evidence showing that the new bonus actually increases sales.</em>

Sliva [168]

Hi there!

A valley farmer has 26 employees and he pays each of them $410 per week.

After paying them for one week he has $162 dollars left. We need to find how much money he had at first.

So the first step is to multiply $410 on 26 since he gives 410 dollars to each employee, which he has 26.

$410 · 26 = $10,660

So he had $10,660 before he paid the workers, but he still had $162 left. To find out his overall total of money he had we need to add $10,660 and $162 which will be $10,822.

The farmer had $10,822

Hope this helped!~

1. Find the value of x.<br> 55°<br> (4x - 5)°<br> O<br> 26<br> O

Paha777 [63]

Answer:

26

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees, use this and set up an equation;

x + ( 4x -5 ) + 55 = 180

Simplify

x + ( 4x - 5 ) + 55 = 180

5x + 50 = 180

Inverse operations;

5x + 50 = 180

-50 - 50

5x = 130

/5 /5

x = 26
