Заполни таблицу и найди дисперсию выборки значений случайной величины \(X\) .

1. \(\,11\) , \(\,13\) , \(\,14\) , \(\,18\) ;

\(X\)	\(X-\overline{X}\)	\((X-\overline{X})^2\)
\(11\)	\(-3\)	\(9\)
\(13\)	[ ]	[ ]
\(14\)	[ ]	[ ]
\(18\)	[ ]	[ ]

\(\sum (X-\overline{X})^2=\) [ ] \(=\) [ ],

\(D=\dfrac{\sum (X-\overline{X})^2}{4}=\) [ ] \(=\) [ ].

2. \(\,19\) , \(\,23\) , \(\,24\) , \(\,26\) , \(\,28\) .

\(X\)	\(X-\overline{X}\)	\((X-\overline{X})^2\)
\(19\)	[ ]	[ ]
\(23\)	[ ]	[ ]
\(24\)	[ ]	[ ]
\(26\)	[ ]	[ ]
\(28\)	[ ]	[ ]

\(\sum (X-\overline{X})^2=\) [ ] \(=\) [ ],

\(D=\dfrac{\sum (X-\overline{X})^2}{5}=\) [ ] \(=\) [ ].
