帮忙翻译两段话，给100块

rejecting a null hypotheis at the "0.01 level" means that if this hypothesis were in fact a true under scrutiny, there is only on percent chance or less that the findings we observe in the sample would bave occured, T or F? Why?

Under what circumstances would you want to test a null hypothesis using the Z-distribution? Under what circumstances would you want to test a null hypothesis using the T-distribution?

在1%的水平下拒绝原假设意味着这个假设事实上是真的，样本中只有1%或以下的可能性发生观察到的情况，正确还是错误？为什么？
什么情况下，用Z分布检验原假设？什么情况下，用T分布检验原假设？
