Sоlve the prоblemThe dаtа fоr the number of hаnd-held gaming devices sold for the past 5 weeks are 15 units, 20 units, 25 units, 17 units, and 17 units respectively. The time series appears to be relatively stable, without trend, seasonal, or cyclical effects; thus, a moving average model would be appropriate. Setting k = 3 the three-period moving average forecast for week 6 is ________.

Suppоse yоu hаve been hired аs а data analyst fоr the well-known company "Poke-ISM4420," known for its extensive Pokémon data and references. Your boss has provided you with a comprehensive dataset of various Pokémon named 'pokemon' (each row is a Pokémon). This dataset contains a variety of variables, including 'type1' that represents the type of Pokémon, 'is_legendary' that indicates if the Pokémon is legendary or not, 'attack' and 'defense' that show the attack and defense values of the Pokémon, and 'name' that signifies the name of the Pokémon. Note: The dataset may contain NA values in 'attack' and 'defense' fields. Your boss has asked you to produce R code that does the following for the 'pokemon' data set: Reduce the dataset to: Retain only the non-legendary Pokémon (is_legendary column where the value is = 0) Retain only grass type Pokémon (from the type1 column) Retain only the 'attack', 'defense', and 'name' columns. Remove any rows that contain NA values in the 'attack' or 'defense' fields. Store this in a data frame called "pokemon_reduced". Using a seed of 1, perform k-means clustering on the pokemon_reduced data frame for 'attack' and 'defense' values with 4 clusters. Which is the largest cluster? Is this a good clustering solution? How do you know this? 1-3 sentences. Add a new column to the pokemon_reduced data frame that denotes the cluster each Pokémon belongs to. Create an elbow plot for the pokemon_reduced data frame to visualize the within-cluster sum of squares. Generate a scatter plot of 'attack' against 'defense' for the pokemon_reduced data frame, where the points are colored by their cluster. Compute the average 'attack' for each cluster of the pokemon_reduced data frame and arrange them in descending order. Create a bar plot of this data, where the x-axis is the cluster and the y-axis is the average 'attack'. Your answer should be presented in the form of R code and accompanied by an explanation of the findings from each task. Your responses to the questions that require non-code text can be comments in the code if you would like. I have no preference.
