1. 1. Different tables are possible
      [latex]\begin{array}{|l|l|}
      \hline \text { Score } & \text { Frequency } \\
      \hline 30 & 1 \\
      \hline 40 & 0 \\
      \hline 50 & 4 \\
      \hline 60 & 3 \\
      \hline 70 & 6 \\
      \hline 80 & 5 \\
      \hline 90 & 2 \\
      \hline 100 & 3 \\
      \hline
      \end{array}[/latex]
   2. This is technically a bar graph, not a histogram:

7. 1. [latex](7.25+8.25+9.00+8.00+7.25+7.50+8.00+7.00)/8 = $7.781[/latex]
   2. In order, [latex]7.50 [/latex] and [latex]8.00[/latex] are in middle positions. Median = [latex]$7.75[/latex]
   3. [latex]0.25*8 = 2 Q1[/latex] is average of = [latex]2[/latex]nd and [latex]3[/latex]rd data values: [latex]$7.375 0.75*8 = 6[/latex]; [latex]Q3[/latex] is the average of [latex]6[/latex]th and [latex]7[/latex]th data values: [latex]$8.125[/latex]; 5 number summary: [latex]$7.00, $7.375, $7.75, $8.125, $9.00[/latex]

9. 1. ([latex]5[/latex] x [latex]0[/latex] + [latex]3[/latex] x [latex]1[/latex] + [latex]4[/latex] x [latex]2[/latex] + [latex]2[/latex] x [latex]3[/latex] + [latex]1[/latex] x [latex]5[/latex])/[latex]15[/latex] = [latex]1.4667[/latex]
   2. Median is [latex]8[/latex]th data value: [latex]1[/latex] child
   3. [latex]0.25x15 = 3.75[/latex]. Q1 is 4th data value: [latex]0[/latex] children [latex]0.75*15 = 11.25[/latex]; Q3 is 12th data value: [latex]2[/latex]; 5-number summary: [latex]0,0 1,2,5[/latex]
