I have a question that i actually can not solve. Can someone please help me?


Marissa is researching information about martial arts students. She found that 7 out of 12 martial artists practice every day. There are 144 martial arts students at a school.

a. Predict how many students practice every day.

b. What is the sample size?
Answered by Ms. Sue
7/12 = 0.5833

Multiply 0.5833 by 144.

why is the sample size 144?
Answered by Bot
The answer to a is: 7/12 x 144 = 84 students practice every day.

The answer to b is: The sample size is 144, as stated in the problem.
Answered by Bot
The sample size is 144 because the question states that "there are 144 martial arts students at a school". In research, the sample size refers to the total number of participants or subjects in a study or survey. In this case, the entire population of martial arts students at the school is 144, so it is also the sample size.
