Chad’s Bakery makes a variety of bread types that it sells to supermarket chains in the area. One of Chad’s 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 Bakery.

a. Which bread type has the highest average daily demand?

b. Develop a frequency distribution for each bread type.

c. Which bread type has the highest standard deviation in demand?

d. Which bread type has the greatest relative variability? Which type has the lowest relative variability?

e. 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.

f. Create a new variable called Total Loaves Sold. On which day of the week is the average for total loaves sold the highest?
