Series 4 has a next-generation accelerometer and gyroscope, with twice the dynamic range, measuring up to 32 g-forces and can sample motion data eight times faster.

S4搭载了下一代的加速感应器和陀螺仪，动态范围提升两倍，可测量32g的力，并能以八倍的速度采集运动数据。

Statistical Inference: Probability serves as the foundation of statistical inference, enabling researchers to draw conclusions about populations based on sample data.

统计推断：概率作为统计推断的基础，使研究人员能够根据样本数据得出有关人群的结论。

And then this formula would probably work out pretty well, at least given your sample data points, of figuring out what the variance is.

然后这个公式可能会很好地计算出方差是多少，至少给定你的样本数据点。

And then with that assumption that the null hypothesis is correct, we're going to see what is the probability of getting this sample data right over here.

然后假设零假设是正确的，我们将看看在这里得到这个样本数据的概率是多少。
