Problem 15BSC

 

Relative Frequencies for Comparisons.Construct the relative frequencies and answer the given questions.

Oscar Winners Construct one table (similar to Table) that includes relative frequencies based on the frequency distributions from Exercises 1 and 2, and then compare the ages of Oscar-winning actresses and actors. Are there notable differences?

Table

IQ Scores from the Low Lead Group and the High Lead Group

Exercise

Exercise1

identify the class width, class midpoints, and class boundaries for the given frequency distribution. The frequency distributions are based on real data from Appendix B.

Exercise 2

identify the class width, class midpoints, and class boundaries for the given frequency distribution. The frequency distributions are based on real data from Appendix B.

Step-by-Step Solution:

Answer :

Step 1 of 1 :

Given, the ages of Oscar-winning actresses and the frequency

Age when Oscar was won

We have to find the relative frequency for comparison

The total frequency = 82

Relative frequency =

Example :

               Relative frequency =

                                               = 32.92

 

class width : the difference between the upper and lower class limit.

Example : 29-2

                  = 9

class midpoints : (lower class limit + upper class limit)/ 2 

Example : (20+29)/2

              = 24.5

 class boundaries :

Upper class boundary = Upper limit + ()  unit of measurement

Ex: 4.9 is the upper class limit and unit of measurement is 0.1

Therefore ,

Upper class boundary = 29 + ()...
