Only the point estimates for the mean execution times are shown.

Agree to use broad estimation ranges rather than single-point estimates and to refine them periodically as the project progresses.
同意给出一个交货日期区间,而不是一个时间点。 可以随着项目的进展而缩短交货区间。
And for those point estimates, their distributions or approximate distributions are obtained. The confidence upper limits of the blind area radius Rm are obtained by using the classical approach.
对于这些估计,给出它们的分布或近似分布,用经典方法可得到盲区半径的置信上限。
Diet, as we said before, is having a big impact, so estimates are that you can attribute two point six million deaths per year globally to low intake of fruits and vegetables.
如我们之前所说,饮食对健康至关重要,所以大致估计每年全球,有260万人的死亡可归结于,水果与蔬菜的摄入过少
