The alternative hypothesis is the hypothesis that we want to test, which is that there is a significant difference between the mean time to access the website with the old design and the mean time to access the website with the new design, in favor of the new design. Therefore, the correct choice is D as it indicates that the mean time to access the website with the new design is less than the mean time to access the website with the old design.
