kirti knows the following information from a study on cold medicine that included 60 participants: . 30 participants in total received cold medicine. . 26 participants in total had a cold that lasted longer than 7 days. . 14 participants received cold medicine but had a cold that lasted longer than 7 days. can you help kirti organize the results into a two - way frequency table? received cold medicine did not receive cold medicine cold lasted longer than 7 days cold did not last longer than 7 days
Answer
Explanation:
Step1: Calculate number of participants who didn't receive medicine
Total participants = 60, received medicine = 30. So, did not receive medicine = 60 - 30 = 30.
Step2: Calculate number of participants with cold > 7 days who didn't receive medicine
Total with cold > 7 days = 26, received medicine and cold > 7 days = 14. So, didn't receive medicine and cold > 7 days = 26 - 14 = 12.
Step3: Calculate number of participants who received medicine and cold ≤ 7 days
Received medicine = 30, received medicine and cold > 7 days = 14. So, received medicine and cold ≤ 7 days = 30 - 14 = 16.
Step4: Calculate number of participants who didn't receive medicine and cold ≤ 7 days
Did not receive medicine = 30, didn't receive medicine and cold > 7 days = 12. So, didn't receive medicine and cold ≤ 7 days = 30 - 12 = 18.
Answer:
| Received cold medicine | Did not receive cold medicine | |
|---|---|---|
| Cold lasted longer than 7 days | 14 | 12 |
| Cold did not last longer than 7 days | 16 | 18 |
