We did not include the minimum wind measurements in the analysis since they are highly correlated with the average wind measurements. What is the correlation between min_wind_speed and avg_wind_speed (to two decimals)? (Compute this using one-tenth of the original dataset, and dropping all rows with missing values.)

This line of code creates a k-means model with 12 clusters:

This line of code creates a k-means model with 12 clusters:kmeans = KMeans (k=12, seed=1) What is the significance of “seed=1”?  This sets the seed to a specific value, which is necessary to reproduce the k-means results  This specifies that the first cluster centroid is set to sample #1  This means that this is the…
