Question

the conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant. number of calories and location of meal preparation home restaurant total ≥ 500 calories 0.15 0.55 0.28 < 500 calories 0.85 0.45 0.72 total 1.0 1.0 1.0 a nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. which is most likely true? an association cannot be determined because the value 0.55 is similar to the value 0.45. there is an association because the value 0.15 is not similar to the value 0.55. there is an association because the sum of each column is 1.0. an association cannot be determined because the sum of the rows going across is not 1.0.

Explanation:

En un análisis de asociación en tablas de frecuencia condicionales relativas, si las frecuencias relativas condicionales son diferentes entre categorías (en este caso, la proporción de comidas con ≥ 500 calorías preparadas en casa es 0.15 y en restaurante es 0.55), sugiere que hay una relación entre la ubicación de preparación y la cantidad de calorías. Las diferencias en frecuencias indican que la ubicación influye en la cantidad de calorías de la comida.

Answer:

There is an association because the value 0.15 is not similar to the value 0.55.
