Question

two-way tables
a group of 65 football players was polled about which synthetic grass they like to play on, chemgrass or chemstrand. the data from the survey is shown in the venn diagram. use the venn diagram to find the missing values in the frequency table.
what are the values of ( x ), ( y ), and ( z )?
( x = 13 ), ( y = 15 ), and ( z = 17 )
( x = 17 ), ( y = 15 ), and ( z = 13 )
( x = 15 ), ( y = 13 ), and ( z = 17 )
( x = 13 ), ( y = 17 ), and ( z = 15 )

Explanation:

Step1: Identificar valores en el diagrama de Venn

En el diagrama de Venn, el valor solo en Chemstrand es \(15\) (que sería \(x\)), el valor en la intersección es \(13\) (que sería \(y\)) y el valor solo en Chemgrass es \(17\) (que sería \(z\)).

Answer:

\(x = 15\), \(y = 13\), and \(z = 17\)
