Answer:
For Number of Headaches: 53
Marginal Frequency: 0.53
Step-by-step explanation:
You can see the total of no headache patients, with or without medicine. That number is 53. Keep this number when solving for marginal frequency.
A marginal relative frequency can be calculated by dividing a row total or a column total by the Grand total. This means you do 53/100, which is 0.53.
