Comparing two types of automobile engines, a consumer testing service obtained the following pickup ( \(0-100 \mathrm{kmph})\) times (rounded to the nearest tenth of a second):

Use the \(U\) test at the 0.05 level of significance to check whether it is reasonable to say that the population of pickup times of the two engines is identical.
