Question

According to a survey conducted by the Associated Press (AP) and petside in 2009, 63% of dog owners and 53% of cat owners would be at least somewhat likely to give CPR to their pet in the event of a medical emergency. The survey involved a nationwide sample of 1,166 pet owners. Use this information to answer the following questions.

Requried:
a. Produce a well-labeled segmented bar graph to display these percentages.
b. Identify the two categorical variables displayed in the graph.
c. What additional information would you need in orde to construct a 2 x 2 table?

Answer 1

a) Check the bar graph in the picture attached

b) The two categorical variables are:

1) Type of owners

2) Likelihood to give CPR

c) Information on the population( in number or percentage) of the dog/cat owners.

Explanation:

a) the bar chart is drawn with % of owners likely to give CPR to their pets on the y-axis and the owner types on the x - axis.

b) The two categorical variables are:

1) Type of owners

2) Likelihood to give CPR

c) To construct a 2 x 2 table, the percentage (or number) of either dog owners or cat owners.

Since we know that the total number of pet owners that were sampled = 1166.

If the number of dog owners is known, it can be subtracted from the total number of pet owners to know the number of cat owners and vice versa. If this information is gotten, then the 2 x 2 table can be constructed.
