    It was a fine night. Carl was on his way home from his friend's party.

    While Carl was walking along the path near his house, he saw a 1 in the sky. It landed on the road at once. Three aliens came out. Carl was 2, because he could understand their language. He learned that they had decided to take all the 3 out of the city.

    Carl was worried about this. He called his friends quickly. While he was 4 for them, he looked at the aliens. They pointed at a tree, and then the tree, like a bird, flew quickly 5 the UFO.

有如下四个命题：

①甲乙两组数据分别为甲：28，31，39，42，45，55，57，58，66；乙：29，34，35，48，42，46，55，53，55，67，则甲乙的中位数分别为45和44．

②相关系数r=﹣0.83，表明两个变量的相关性较弱．

③若由一个2×2列联表中的数据计算得K²的观测值k≈4.103，那么有95%的把握认为两个变量有关．

④用最小二乘法求出一组数据（x_i，y_i），（i=1，…，n）的回归直线方程$\stackrel{\wedge }{y}$=$\stackrel{\wedge }{b}$x+$\stackrel{\wedge }{a}$后要进行残差分析，相应于数据（x_i，y_i），（i=1，…，n）的残差是指$\stackrel{\wedge }{e_i}$=y_i﹣（$\stackrel{\wedge }{b}$x_i+$\stackrel{\wedge }{a}$）．

以上命题“错误”的序号是____ ．
