问题如下图：
题目中从哪里得出CI是95%？
NO.PZ2020011101000015问题如下 Suppose all resiautocorrelations are 1.5/T1.5/ \sqrt T1.5/T, where T is the sample size. Woulthese violate the confinban in Aplot? No, the confinban are ±1.96/T\pm 1.96/ \sqrt T±1.96/T anso these woulnot. If many autocorrelations are jointly relatively large, then this series is likely autocorrelate A Ljung-Box test woullikely tethe joint autocorrelation.“resiautocorrelations are（1.5/跟号T）”这句话是说e1和e2，e2和e3等等，各个e之间的correlation结果是（1.5/跟号T）？而不是 H0:p1=p2=…pn=0，Ha至少一个p不等于0的假设检验结果是（1.5/跟号T）？

这道题目能翻译下吗？要考察的点是什么啊？已经看了之前的问题和回答，还是不是很清楚题目在问啥，谢谢。
请问一下confinban的公式在笔记上哪里呢
回答思路不是很懂，这里为什么要用t test呢？因为题干里提到all resiautocorrelation，为什么不用F test呢？
