Final answer:
News and Science magazines likely have different variances in length due to the nature of their contents: News varies with weekly events, while Science tends to be more consistent.
Step-by-step explanation:
The question is asking to compare the variances in length (i.e., number of pages) between different types of magazines. Variance is a concept in statistics that measures how far a set of numbers (in this case, the number of pages) are spread out from their average value.
In considering various magazine types, I find that News and Science magazines are likely to have different variances in length. News magazines, such as Time, tend to cover current events and can vary greatly in length depending on the week's occurrences.
Science magazines, however, often report on detailed research findings and studies which may lead to more consistent length due to the nature of scientific reporting. Given these attributes, it would be reasonable to conclude that News magazines have a higher variance in length, while Science magazines maintain a more consistent page count.
