Answer:
There is enough evidence at the 0.05 significance level that the percentage is less than 25%.
Step-by-step explanation:
<em>The question has no options. However, there are enough details to arrive at a conclusion.</em>

What can we conclude about the claim of the publisher.
From the question, we understand that the null hypothesis is rejected.
In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.
In this case, the determined value 25% and the level of significance is 0.05
<em>So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.</em>
Answer: 4/9
<u>Step-by-step explanation:</u>
Let x represent the denominator. Then the fraction is: (x - 5)/x
Add 1 to the numerator and denominator → (x - 5 + 1)/(x + 1) = 1/2
Cross Multiply: 1(x + 1) = 2(x - 4)
Distribute: x + 1 = 2x - 8
Subtract x from both sides: 1 = x - 8
Add 9 to both sides: 9 = x
Numerator: x - 5 → 9 - 5 = 4
Denominator: x → 9
So the fraction is: 4/9
