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

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%.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
