Question

i need help on this, please explain. it would mean a lot. i'll mark you're answer brainlist !!it's due in a few minutes.

Answer 1

The relative frequency is calculated as the quotient between the absolute frequency of a class and the sample size (or sum of all the absolute frequencies).

In this case, the sample size is:

$47+123+175+91+34=470$

Then, the relative frequency for getting an A is theq quotient between the absolute frequency of A (47) and the sample size (470):

$f_A=\frac{47}{470}=0.1$

For C is:

$f_c=\frac{175}{470}\approx0.37$

Answers:

Relative frequency of A: 0.1

Relative frequency of C: 0.37

The total is 470.

The relative frequency of the total is, b y definition, 1 because it is N/N=470/470=1.
