Dafna11 [192]

Answer:

Here, F = 2.911

F > 2.739502 , so reject null hypothesis ( H0)

There is ample evidence to indicate a disparity in the means for the different forms of mails.

Step-by-step explanation:

Null hypothesis -  H₀: μ₁ = μ₂ = μ₃ = μ₄

Alternative hypothesis - H₁: At least one mean is different.

df1 is factor degree of freedom and df2 is error degree of freedom.

Decision rule -  Reject H₀ if F > F₀.₀₅, (df1, df2)

F0.05, df1,df2   is f critical value at \alpha = 0.05

Here df1 = 3 , and df2 = 68

Using Excel,

F₀.₀₅, ₃, ₆₈ = FINV( 0.05, 3 , 68 ) = 2.739502302

So reject H0 if F > 2.739502

Here, F = 2.911

F > 2.739502 , so reject null hypothesis ( H0)

There is ample evidence to indicate a disparity in the means for the different forms of mails.

Goryan [66]

Answer:

<em>The gaph is shown in the image below</em>

Step-by-step explanation:

<u>Graph of Inequalities</u>

Let's graph the region of the inequality

0.8m + 0.4p \leq 2,000

Since there is no indication, we'll assume the variable p to be in the horizontal axis and m in the vertical axis. Let's solve for m

\displaystyle m=\frac{2,000-0.4p}{0.8}

Since both m and p are positive, we can assume

2,000-0.4p\geq 0

Or, equivalently

p \leq 5,000

Thus, we can give p any value between 0 and 5,000 to get the corresponding values for m. Let's select the values p=0, p=1,000, p=5,000 to get the points

( 0 ; 2,500 ) ( 1,000 ; 2,000 ) ( 5,000 ; 0 )

With these points we can plot the line representing the function. To know which area must be shaded, we only need to test one point below or above the line. If it fulfills the inequality, then the whole area is shaded.

Let's test the point ( 1,000 ; 1,000 )

0.8\cdot 1,000 + 0.4\cdot 1,000 \leq 2,000

1,200 \leq 2,000

Since the condition is met, the area below the line must be shaded as the solution of the inequality
