on the first day of science class, leos teacher asked the class about their favorite science topics. of the whole class, 6 students chose chemistry, 3 students chose earth science, 9 students chose physics, and 12 students chose biology. complete the relative - frequency table for the data. favorite science topics topic chemistry earth science physics biology relative frequency % % % %
Answer
Explanation:
Step1: Calculate total number of students
$6 + 3+9 + 12=30$
Step2: Calculate relative - frequency of Chemistry
Relative frequency of Chemistry $=\frac{6}{30}\times100% = 20%$
Step3: Calculate relative - frequency of Earth science
Relative frequency of Earth science $=\frac{3}{30}\times100% = 10%$
Step4: Calculate relative - frequency of Physics
Relative frequency of Physics $=\frac{9}{30}\times100% = 30%$
Step5: Calculate relative - frequency of Biology
Relative frequency of Biology $=\frac{12}{30}\times100% = 40%$
Answer:
| Topic | Chemistry | Earth science | Physics | Biology |
|---|---|---|---|---|
| Relative frequency | 20% | 10% | 30% | 40% |
