【单选题】有如下事件过程：Private Sub Form_Load() Show Dim Arr() As Variant Arr = Array(1, 3, 5, 7, 9, 11, 13, 15) Call converse(Arr) For i = 0 To 7 Print arr(i); Next iEnd Sub 以上程序的功能是，通过调用Converse过程，将数组Arr中的元素逆序存放并输出...
A.
Private Sub converse(dim a() as Variant ) Dim T For i = LBound(A) To UBound(A) T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
B.
Private Sub converse(dim a() as Variant) Dim T Dim J As Integer J = (LBound(A) + UBound(A)) / 2 For i = LBound(A) To J T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
C.
Private Sub converse(a() As Variant) Dim T For i = LBound(A) To UBound(A) T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
D.
Private Sub converse(a() As Variant) Dim T Dim J As Integer J = Int((LBound(A) + UBound(A)) / 2) For i = LBound(A) To J T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub

【单选题】卡方拟合检验的原假设和备择假设为（ ）。
A.
\( H_0 :\mu =\mu _0 ,\quad H_1 :\mu \ne \mu _0 \)（\( \mu \) 是总体均值）
B.
\( H_0 :\sigma ^2=\sigma _0^2 ,\quad H_1 :\sigma ^2\ne \sigma _0^2 \)（\( \sigma^2 \) 是总体方差）
C.
\( H_0 :X\sim \left( {{\begin{array}{*{20}c} {a_1 } & {a_2 } & \cdots & {a_m } \\ {p_1 } & {p_2 } & \cdots & {p_m } \\ \end{array} }} \right),\quad H_1 :X\mbox{ 不服从 }\left( {{\begin{array}{*{20}c} {a_1 } & {a_2 } & \cdots & {a_m } \\ {p_1 } & {p_2 } & \cdots & {p_m } \\ \end{array} }} \right) \)
D.
\( H_0 :F(x)\le F_0 (x),\quad H_1 :F(x)>F_0 (x) \)
