Assume you have been hired by a local purveyor of avocado toast, let's say [Jam](https://www.jamonmain.com), to perform research on avocado prices. For this lab you will explore a dataset containing historical sales prices and volumes of avocados. More details about the complete dataset can be found here [https://www.kaggle.com/neuromusic/avocado-prices/home](https://www.kaggle.com/neuromusic/avocado-prices/home).
A subset of this dataset is available at [http://math.montana.edu/ahoegh/teaching/timeseries/data/avocado_west.csv](http://math.montana.edu/ahoegh/teaching/timeseries/data/avocado_west.csv). The dataset contains the following variables:
- Date: (note, the `read_csv()` function may read this as a date-time object)
- AveragePrice: the price of a single avocado
- TotalVolume: the amount of avocados sold
- Type: category to denote conventional or organic
#### 1. Data Visualization (40 points)
Create a visualization to display the dataset and include a 2 to 3 sentence caption to describe your figure. Note there are a few different things you could choose to focus on here, but clearly describe (in the graph and caption) would you are focusing on.
#### 2. Time Series Decomposition (40 points)
Create a visual decomposition of the time series and discuss what you see.
(STAT 536). Write out the decomposition
#### 3. Forecasting (20 points)
###### a.
Discuss a strategy for estimating the volume of avocados sold weekly for a year, given that you know the prices.
###### b.
Discuss a strategy for estimating the volume of avocados sold weekly for a year, given that you don't know the prices.
