Question

I am working with Mario Triola's 11th ed. of ElementaryStatistics. One problem asks us to construct a relative frequencydistribution. I am starting with a lower class limit of 0.7900 lb.,and the class width is 0.0050 lb. (data set contains If I'mstarting out with 0.7900, would the first class look like this,below?                      Weight                                    Rel.Freq.                      0.7900-0.7949                      0.7950-0.8000(andso on...) I haven't taken a math course in 20 years, so I have torefresh my memory. (And I know that the rel. frequency is the classfrequency divided by the sum of all frequencies). Thanks!

Explanation / Answer

You simply have to count the number of elements in your data set that are between 0.7900 and 0.7949, then divide that number by the total number of elements, as you wrote.
