Question

A book Thandi is reading features totem poles from two regions in the Pacific Northwest.

The two-way table shows some of the animals carved in the totem poles and the regions where the totem poles are located.
Thandi states that 20% of Alaskan totem poles featured in the book have eagles carved in them. Use the drop-down menus to explain and correct Thandì's error.

Answer 1

Explanation:

Thandi's statement that 20% of Alaskan totem poles featured in the book have eagles carved in them is not accurate.

A two-way table, also known as a contingency table, is used to organize and display the relationship between two categorical variables. The table shows the frequency or count of observations for each combination of the two variables. In this case, the two variables are the animals carved in the totem poles and the regions where the totem poles are located.

To find the percentage of Alaskan totem poles that have eagles carved in them, we need to divide the number of Alaskan totem poles with eagles by the total number of Alaskan totem poles and multiply by 100. This can be calculated as:

(Number of Alaskan totem poles with eagles / Total number of Alaskan totem poles) * 100

Without the data for the two-way table it's impossible to check if the statement is correct or not. It's important to note that without the data it is also impossible to know the context of the statement and the information provided in the book.

Answer 2

=Have Eagles

=50%

Explanation:

Thandi may have found the percent of the total totem poles that have eagles. The actual percent of Alaskan totem poles that have eagles carved in them is 50%.
