1. Answer:

   Find\:the\;mean\:of\:the\:Given\:data\:using\: any\:method}[/tex]

   [tex]\begin{gathered}\boxed{\begin{array}{c|c|c|c|c|c|c|c}\bf {Class\:interval:-} &\sf 10-10 &\sf 20-29 &\sf 30-39 &\sf 40-49 &\sf 50-59 &\sf 60-69 &\sf 70-79 \\&&&&&&&\\ \bf {Frequency:-} &\sf 5 &\sf 65 &\sf 222 &\sf 112 &\sf 53 &\sf 40 &\sf 3 \end {array}}\end{gathered}[/tex]

2. To Find:-

   • Find the mean of the data.

   Solution:–

   As we know that:–

   • [tex]\sf \: Mean = \dfrac { Sum \: of \: Class \: Interval } { Frequency } [/tex]

   Here ,

   • Sum of class interval is 19500

   • Sun of frequency is 500

   [tex]\longrightarrow\sf \: Mean = \cancel\dfrac { 19500 } { 500 } [/tex]

   [tex]\longrightarrow\sf \: Mean = 39 [/tex]

   Hence ,

   • Mean is 39
