Answer:
280 said YES
120 said NO
56 drink at least 3 cups
224 do not drink at least 3 cups
56/400 drink 3 cups a day or 7/50 simplified.
Step-by-step explanation:
To complete the frequency table use the sample size 400, 7/10 say yes, and 20% drink at least 3 cups.
- If 7/10 people say yes, then 3/10 people say no. 7/10 as a decimal is 0.7. Multiply 0.7 by the sample size 400 to find the amount of people.
0.7(400) = 280
This means 280 people say yes. And 120 must say no.
- If 20% drink at least 3 cups then 0.20 is the decimal conversion. To find the amount multiply 0.20 by the same size 280 (the amount who said yes).
0.2(280) = 56
This means 56 people said YES and drink at least 3 cups. And 224 who said YES do not.
This also means 56 out of the whole sample size of 400 drink 3 cups. THe fraction is 56/400 or 7/50 simplified.
