Question

After opening day, theme park attendance has been tracked at a new park in Destin, FL..

Answer 1

13.9% marginal

Explanation:

The percentage of tickets sold to Seniors can be found as:

`p(s)=(S)/(N)\cdot 100`

where

S is the number of all tickets sold to seniors

N is the total number of tickets sold

By looking at the table, we see that:

S = 32 + 14 + 54 = 100 is the number of tickets sold to seniors

N = 35 + 87 + 62 + 56 + 177 + 205 + 32 + 14 + 54 = 722 is the total number of tickets sold

Therefore, the percentage is:

`p(s)=(100)/(722)\cdot 100 =13.9\%`

The three different types of frequencies are defined as:

- Joint: the frequency of a single category calculated with respect to the total number --> this is not the case

- Marginal: the frequency of an entire row/column over the total --> this is the case

- Conditional: the frequency of a single category over a subset of the total --> this is not the case

So, the correct answer is

13.9% marginal
