The sample size would have to be quadrupled . 样本量必须增大三倍。
Sampling techniques and sample size requirements vary with the techniques used . 取样方法和取样多少的要求因所采用的测试方法而异。
If, however, the sample sizes are large enough, we do not need the assumption of normality . 如果样本容量充分大,就不必做正态假设。
A sample size needs to be established when this method of mass flow measurement is used . 在使用这种质量流量测量方法时,需要测定试样的大小。
In general, the t distribution is flatter than the normal distribution, and there is a different t distribution for every possible sample size . 一般地说,t分布比正常分布更平坦一些,对于不同的样本容易都有一个不同的相应t分布。
