    Japolli Bakery makes a variety of bread types that it sells to supermarket chains in the area. One of the problems is that the number of loaves of each type of bread sold each day by the chain stores varies considerably, making it difficult to know how many loaves to bake. A sample of daily demand data is contained in the file,Japolli Bakery.



    1. Develop a frequency distribution for each bread type using& appropriate intervals.

    2. Select which bread type has the greatest and lowest relative variability.

    3. Assuming that these sample data are representative of demand during the year, determine how many loaves of each type of bread should be made such that demand would be met on at least 75% of the days during the year.

    4. Submit your work in a Word document and attach your Excel file.

1. Steps to for the frequency distribution.
a. Find the range of the data using the below formula
b
. Find the number of classes required using the below formula
c. Determine the approximate class interval size
d. Determine the starting point – The lower class limit or class boundary should cover the smallest value in the raw.
e. Determine the remaining class limits (boundary): After you have determined the lowest class boundary, you can compute the upper class boundary by adding the class interval size. Adding the class interval size repeatedly until the largest value of the data is observed in the class may determine the remaining lower and upper class limits.
f. Distribute the data into respective class: All the observations are divided into respective classes.
