Question

students in 10th and 11th grade were asked whether they have a job. the raw data was converted to relative frequencies and recorded in the table below. given the conditional relative frequency table by column, what does the 0.14 represent? 10th grade 11th grade total job 0.14 0.25 0.20 no job 0.86 0.75 0.80 total 1 1 1 given that a student is a 10th grader, there is a 14% chance he or she has a job. given that a student has a job, there is a 14% chance he or she is a 10th grader. 14% of the students surveyed are 10th graders who have a job. 14% of the students are 10th graders.

Explanation:

Step1: Comprender tablas de frecuencia condicional

En una tabla de frecuencia relativa condicional por columna, las frecuencias se calculan en función de la columna.

Step2: Analizar la celda 0.14

La celda 0.14 está en la columna de 10th grade y fila de Job. Significa que dado que un estudiante es de 10º grado, la probabilidad de que tenga un trabajo es del 14%.

Answer:

Given that a student is a 10th grader, there is a 14% chance he or she has a job.
