Set of data consists of 45 observations between $0 and $29. how many classes would you recommend for the frequency distribution?

As, number of Observation=45

Minimum value>0

And Maximum value<29

I would prefer classes from[0-3,3-6,6-9,9-12,12-15,15-18,18-21,21-24,24-27,27-30] or[0-5,5-10,10-15,15-20,20-25,25-30].

So YOU can choose either 10 classes or 6 classes.

As 6 classes will be perfect because number of observation is quite large so each class will contain adequate number of observations and you can draw any kind of graph easily.

step-by-step explanation:

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
