The frequency table represents the job status of a number of high school students. Job Status Looking for Job Not Looking for Job Total Currently Employed 12 28 40 Not Currently Employed 38 72 110 Total 50 100 150 Which shows the conditional relative frequency table by column?

A
Job Status Table with 4 columns and 4 rows.Row 1: Column 1, empty; Column 2, 'Looking for Job'; Column 3, 'Not Looking for Job'; Column 4, 'Total' Row 2: Column 1, 'Currently Employed'; Column 2, '0 point 3'; Column 3, '0 point 7'; Column 4, 'almost equal to 0 point 2 7' Row 3: Column 1, 'Not Currently Employed'; Column 2, 'almost equal to 0 point 3 3'; Column 3, 'almost equal to 0 point 6 5'; Column 4, 'almost equal to 0 point 7 3' Row 4: Column 1, 'Total'; Column 2, '1 point 0'; Column 3, '1 point 0'; Column 4, '1 point 0'
B
Job Status Table with 4 columns and 4 rows.Row 1: Column 1, empty; Column 2, 'Looking for Job'; Column 3, 'Not Looking for Job'; Column 4, 'Total' Row 2: Column 1, 'Currently Employed'; Column 2, '0 point 1 2'; Column 3, '0 point 2 8'; Column 4, '0 point 4' Row 3: Column 1, 'Not Currently Employed'; Column 2, '0 point 3 8'; Column 3, '0 point 7 2'; Column 4, '1 point 1' Row 4: Column 1, 'Total'; Column 2, '0 point 5 0'; Column 3, '1 point 0 0'; Column 4, '1 point 5'
C
Job Status Table with 4 columns and 4 rows.Row 1: Column 1, empty; Column 2, 'Looking for Job'; Column 3, 'Not Looking for Job'; Column 4, 'Total' Row 2: Column 1, 'Currently Employed'; Column 2, '0 point 2 4'; Column 3, '0 point 2 8'; Column 4, 'almost equal to 0 point 2 7' Row 3: Column 1, 'Not Currently Employed'; Column 2, '0 point 7 6'; Column 3, '0 point 7 2'; Column 4, 'almost equal to 0 point 7 3' Row 4: Column 1, 'Total'; Column 2, '1 point 0'; Column 3, '1 point 0'; Column 4, '1 point 0'
D
Job Status Table with 4 columns and 4 rows.Row 1: Column 1, empty; Column 2, 'Looking for Job'; Column 3, 'Not Looking for Job'; Column 4, 'Total' Row 2: Column 1, 'Currently Employed'; Column 2, '0 point 0 8'; Column 3, 'almost equal to 0 point 1 9'; Column 4, 'almost equal to 0 point 2 7' Row 3: Column 1, 'Not Currently Employed'; Column 2, 'almost equal to 0 point 2 5'; Column 3, '0 point 4 8'; Column 4, 'almost equal to 0 point 7 3' Row 4: Column 1, 'Total'; Column 2, 'almost equal to 0 point 3 3'; Column 3, 'almost equal to 0 point 6 7'; Column 4, '1 point 0'

The conditional relative frequency table was generated by row using frequency table data comparing the hat size and shirt size of children on a baseball team. Hat Size and Shirt Size Child-sized Hat Adult-sized Hat Total Medium Shirt almost equal to 0 point 6 7 almost equal to 0 point 3 3 1 point 0 Large Shirt 0 point 2 0 point 8 1 point 0 Total 0 point 4 8 0 point 5 2 1 point 0 The coach attempts to determine an association between shirt size and hat size. Which is most likely true?

A
There is likely an association because 0 point 8 is not similar to almost equal to 0 point 3 3 .
B
An association cannot be determined because the sum of each column is not 1 point 0 .
C
An association cannot be determined because 0 point 4 8 is similar to 0 point 5 2 .
D
There is likely an association because 0 point 8 is not similar to 0 point 2 .

A conditional relative frequency table is generated by column from a set of data. The conditional relative frequencies of the two categorical variables are then compared. If the relative frequencies being compared are 0 point 2 1 and 0 point 7 9 , which conclusion is most likely supported by the data?

A
There is likely an association between the categorical variables because the relative frequencies are not similar in value.
B
An association cannot be determined between the categorical variables because the relative frequencies are not similar in value.
C
An association cannot be determined between the categorical variables because the sum of the relative frequencies is 1 point 0 .
D
There is likely an association between the categorical variables because the sum of the relative frequencies is 1 point 0 .
