Question

A partial relative frequency distribution is given. (a) What is the relative frequency of class D ? (b) The total sample size is 800 . What is the frequency of class D? (c) Show the frequency distribution.

Answer 1

The relative frequency of class D is 1.625%, the frequency of class D is 13, and the frequency distribution includes the frequencies of all classes.

Step-by-step explanation:

a) To find the relative frequency of class D, we divide the frequency of class D by the total sample size. In this case, the frequency of class D is 13. Dividing 13 by 800 gives us a relative frequency of 0.01625, or 1.625%.

b) The frequency of class D is 13.

c) To show the frequency distribution, we list each class along with its frequency. In this case:

Class D: 13

Class 65: 65

Class 15: 15

Class 17: Answers will vary
