问题如下：

Here is a table discribing sample statistics from two bonds' rate of return which are both normally distributed over the past decades. If an investor is considering whether the variance of bond A is greater than 3.24%,

which of the following conclusion is least appropriate (significant level=5%) ?

选项：

It is appropriate to use the F-test.

The hypothesis is : $H_{0} : σ^{2} \leq 3.24 %.$

It is appropraite to use the chi-square test.

解释：

The chi-square test is used to test hypotheses concerning a single population variance.So C is correct.

The null hypothesis can place in whatever you want to reject, so B is correct.

题干问选择least appropriate,So choose A.

题目是不是出错了。。

同学你好，

本题的答案是选择A。

C和B选项的描述本身都是correct的，所以不选。
