Question

4 fill in the blank 1 point class frequency, f 1 - 5 21 6 - 10 16 11 - 15 28 16 - 20 13 for the frequency table above, the... relative frequency of the 1st class is 1.05 round to 3 decimals relative frequency of the 2nd class is 800 round to 3 decimals relative frequency of the 3rd class is 1.40 round to 3 decimals relative frequency of the 4th class is 0.65 round to 3 decimals

Explanation:

Step1: Calculate total frequency

$21 + 16+28 + 13=78$

Step2: Calculate relative frequency of 1st class

$\text{Relative Frequency}=\frac{\text{Frequency of class}}{\text{Total Frequency}}$, so for 1st class $\frac{21}{78}\approx0.269$

Step3: Calculate relative frequency of 2nd class

For 2nd class $\frac{16}{78}\approx0.205$

Step4: Calculate relative frequency of 3rd class

For 3rd class $\frac{28}{78}\approx0.359$

Step5: Calculate relative frequency of 4th class

For 4th class $\frac{13}{78}\approx0.167$

Answer:

Relative frequency of 1st class: $0.269$
Relative frequency of 2nd class: $0.205$
Relative frequency of 3rd class: $0.359$
Relative frequency of 4th class: $0.167$
