使用函數
pt
計算信心區間的累積機率分佈：

8.
使用函數
rt
建立含有 T-測試的亂數向量。
<region id="ID0EC3EGB" top="2227.2000000000003" left="38.400000000000006" xml:lang="zh_TW" height="137.2" width="145.37" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="168" xml:lang="zh_TW"> <eval xml:lang="zh_TW" xmlns="http://schemas.mathsoft.com/math50"> <apply xml:lang="zh_TW"> <id labels="FUNCTION" xml:space="preserve" xml:lang="zh_TW" label-is-contextual="true">rt</id> <sequence xml:lang="zh_TW"> <real xml:lang="zh_TW">7</real> <id labels="VARIABLE" xml:space="preserve" xml:lang="zh_TW" label-is-contextual="true">ν</id> </sequence> </apply> <unitOverride xml:lang="zh_TW"> <placeholder xml:lang="zh_TW" /> </unitOverride> </eval> <resultFormat xml:lang="zh_TW"> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" xml:lang="zh_TW" /> </resultFormat> </math> </region>
重新計算工作表會導致函數 rt 傳回一組不同的亂數。
