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}

7

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}?
