Kirti knows the following information from a study on cold medicine that included 60 participants: 30 participants in total rece
ived 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?
1 answer:
The frequency table is attached.
Since there were 30 people out of the 60 that received cold medicine, that means that 60-30=30 people did not.
Since 26 people had a cold longer than 7 days, this means 60-26=34 had a cold that was less than or equal to 7 days.
14 people had a cold longer than 7 days and received medicine; this means that 26-14=12 people had a cold longer than 7 days and did not receive medicine.
30-14=16 people received medicine and had a cold less than or equal to 7 days.
30-12=18 people did not receive medicine and had a cold less than or equal to 7 days.

Hello!
To find the slope we divide the difference of the y-values by the difference of the x-values as shown below.
The slope of our line is -3/4.
I hope this helps!
