Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
See the attached photo for the calculations for this test
A table of values can be used to represent variables that are directly proportional.
The complete table of proportions is:
Given that
Let:
<em /><em> Letters</em>
<em /><em> Cost</em>
<em />
Using proportional reasoning, we have:
Where
<em /><em> ratio of proportion</em>
For the first values of C and L, we have:
Divide both sides by 10
So, the equation of proportion is:
<u>When C = 6.75, we have:</u>
Solve for L
<u>When L = 7, we have:</u>
<u>When L = 1, we have:</u>
<u>When L = 500, we have:</u>
<u>When C = 18.90, we have:</u>
Solve for L
Hence, the complete table is:
