PART A:  FREQUENCIES AND HISTOGRAMS

Note: first read the posted textbook chapter (of Bluman) and watch the posted video; your histogram solution should also cover the below mentioned steps:

PROBLEM 1

The (rounded) average price for a box of cookies obtained from random bakeries is listed below:

20       23       11       20       22       20       51       15       28       22       

22       18       70       19       22       28       27       19       23       46

So with the information above i need to supposedly Construct a grouped frequency distribution and a cumulative frequency distribution with 6 classes. how do i start going about that?

Grouped Frequency Distribution

Step 1. Find Range:

Step 2. Compute classes' width (always round-up; if the width computation results in an integer, round it up to the next integer)

Step 3. Create class boundaries

Classes                      Class Boundaries      Frequency

Cumulative Frequency Distribution

Step 1. Find Range:

Step 2. Compute classes' width:

Step 3. Find the frequencies and the corresponding percentage

Classes                      Cumulative Frequency                      Percentage
