You need to construct a table to show continuous data going from \({0}\) to \({10}\). What sign should replace the asterisk *?

\[{0}\leq{weight}~\textless~{5}\]

\[{5}~{*}~{weight}\leq{10}\]

You need to construct a table to show continuous data going from \({20}\) to \({100}\). What sign should replace the asterisk *?

\[{20}\leq{length}~\textless~{50}\]

\[{50}\leq{length}~{*}~{70}\]

\[{70}\leq{length}\leq{100}\]

What's wrong with these continuous groups?

\[{time}\textless{20}\]

\[{20}\leq{time}\leq{50}\]

\[{50}\leq{time}~\textless~{70}\]

\[{70}\leq{time}\textless{100}\]

\[{time}\geq{100}\]

Here's the heights of pupils in the class:

\[{150},~{167},~{141},~{156},~{160},~{177}\]

\[{169},~{166},~{159},~{153},~{163},~{165}\]

\[{164},~{171},~{176},~{155},~{161},~{165}\]

How many pupils' heights are in the group \({160}~\textless~{height}\leq{165}\)?
