Answer:
From the frequency table, let's calculate the row total.
Row total for phone call = 19 + 9 = 28
Row total for no phone call = 8 +6 = 14
To calculate their respective row relative frequencies, let's use:
Row relative freq =
Now, the two-way frequency table will be computed as:
For phone call:
Desirable behavior = ≈0.69
Undesirable behaviour = ≈0.32
No phone call:
Desirable behaviour = ≈ 0.57
Undesirable behaviour = ≈ 0.43
The complete two-way table is attached.
