A sales manager wanted to determine if increasing sales commissions by 5% would increase employee satisfaction. Her analyst dete

rmined the p-value was 0.04. (Use α = 0.05.)
Based on the above output, what is the correct conclusion for the Wilcoxon Signed Rank Test?

a. We do not have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
b. We do not have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
d. We have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.

Answer:

c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.

Step-by-step explanation:

Pvalue is less than the alpha-level:

If the pvalue is less than the alpha-level, we have that there is sufficient evidence of the hypothesis for the population mean/median/standard deviation we are testing.

In this question:

Pvalue less than the alpha-level, so there is evidence that there is a difference in the population median. This means that the correct answer is given by option C.

Which of the following transformations does not
svlad2 [7]

Answer:

(9x, 9y) dilation

Step-by-step explanation:

(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

How to determine if the function has x-axis sym, y-axis sym, and origin sym<br><br> y^2 -xy =2
n200080 [17]

To check for symmetry on the x axis, replace y with –y

-y^2 –x(-y) =2

<span> Apply the product rule, since the equation is not identical tot eh original equation it is not symmetric about the x axis</span>

<span> Now do the same for y axis by replacing x with –x</span>

<span> Again using product rule the equations are not identical, so it is not symmetric about the y axis</span>

<span> To check the origin,</span>

<span> Replace both x & y with –x  & -y</span>

Again using product rule, the equations are not identical so it is not symmetric about the origin

Graph the linear equation and answer each of the following questions. y&gt;2/3 x-2 What is the y-intercept? What is the slope (i
lozanna [386]

Answer:

(i)

y-intercept is -2

(ii)

slope is \frac{2}{3}

(iii)

slope is positive

(iv)

another point is (3,0)

Step-by-step explanation:

We are given equation as

y=\frac{2}{3} x-2

now, we can compare it with slope intercept form of line

y=mx+b

where

m is slope

b is y-intercept

we get

m=\frac{2}{3}

b=-2

So,

(i)

y-intercept is -2

(ii)

slope is \frac{2}{3}

(iii)

we can see that

m=\frac{2}{3}

is a fraction and positive

so, slope is positive

(iv)

we can select any random value of x and find y

that will give us second point

Let's assume

x=3

y=\frac{2}{3}\times 3-2

y=2-2

y=0

So, another point is (3,0)

(v)

Someone help please, dk what to do
Alekssandra [29.7K]

Step-by-step explanation:

equation format: y = mx + b where m is slope and b is the y intercept.

From the points given we find that it is a horizontal line, which means slope or m = 0. So we know so far:

y = 0x + b or y = b

The y-intercept occurs where x = 0. This occurs at y = -7. So the equation for these two points:

EQUATION: y = -7
