d) There is a specific reason why it's so difficult to properly forecast this data using Time Series approach. Explain to me in 2-4 sentences what the problem is. Hint: consider what we are trying to predict (gallons of ice cream sold).
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

![Problem #3: (46
Georgia is well known for its popularhomemade ice cream, made in a small plant in back of the café.
People drive all the way from Atlanta and Macon to buy the ice cream. The two women who own the café
want to develop a forecasting model so they can plan their ice cream production and determine the
number of employees they need to sell ice cream in the café. They have accumulated the following sales
records for their ice cream for the past 12 quarters (3years):

a) Fill out the above table, calculating SES and AES as shown. Make sure to show your work for at
lea st Quarters 3-5 for each forecast.
b) Then calculate the Errors and Average Error for me. Which one of these three methods has the
lea st average error?
c) Calculate the Mean Absolute Deviation for just Alpha = .5, Beta = .5 for me. Do the Errors mostly
cancel each other out when we use Absolute Deviation on them?
d) There is a specific reason why it's so difficult to properly forecast this data using Time Series
approach. Explain to me in 2-4 sentences what the problem is. Hint: consider what we are trying to
predict (gallons of ice cream sold).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5e5ee795-7374-4de4-a8e7-d2f3f155439f%2Fc2befde2-d975-4757-a2e0-c49fd1b47c94%2Fr65qyv_processed.jpeg&w=3840&q=75)
