Answer to Problem 2CYP

Conclusion correct

Explanation of Solution

Given: At a sold-out concert in a 5000-seat concert hall, every 10^th attendee complete a survey.

  $\begin{array}{c}\begin{array}{c}\text{Results}\\ \begin{array}{cc}\text{Choice}& \text{Response}\\ \text{very resonable}& 56\\ \text{resonable}& 185\\ \text{somewhat resonable}& 132\\ \text{unresonable}& 69\\ \text{very unresonable}& 58\end{array}\end{array}\end{array}$

According to table data,

After every 1oth attendee. So, first count toal number of attendee in each reasonable.

  $\begin{array}{cc}\text{Choice}& \text{Response}\\ \text{very resonable}& 56\\ \text{resonable}& 185\\ \text{somewhat resonable}& 132\\ \text{unresonable}& 69\\ \text{very unresonable}& 58\end{array}\begin{array}{c}\text{Total}\\ 560\\ 1850\\ 1320\\ 690\\ 580\end{array}$

Now count number of reasonable attendee = 560+1850+1320 = 3730

Percentage of reasonable attendee $=\frac{3730}{5000}\times 100=75\%$

Hence, conclusion is correct. The price for the tickets are reasonable and should remain same.
