Chapter 11.4, Problem 20E

To determine

To calculate the percentages.

Answer to Problem 20E

Percentage of sandwiches on wheat bread is $55\%$

Percentage of sandwiches are turkey on white bread is $24\%$

Explanation of Solution

Given information :

The two-way table:

		Meat
		Turkey	Ham	Total
Bread	White	0.34	0.11	0.45
	Wheat	0.24	0.31	0.55
	Total	0.58	0.42	1

The two-way table of marginal relative frequencies and joint relative frequencies:

		Meat
		Turkey	Ham	Total
Bread	White	0.34	0.11	0.45
	Wheat	0.24	0.31	0.55
	Total	0.58	0.42	1

From this, take the joint relative value of the category or the marginal relative frequencies that have been asked.

Here, multiply the ratio with 100 in order to get the percentage.

Percentage of sandwiches on wheat bread is $55\%$

Percentage of sandwiches are turkey on white bread is $24\%$
