[x] This LO reads a bit odd I think "Visualize the output of K-means clustering in Python using a colored scatter plot.". I would remove the word "colored".
[x] In the first paragraph of 9.5.1 there is a typo: "intertia" -> "inertia"
[x] Also in 9.5.1, missing the word in bold: "computing the mean of each variable over the data points in the cluster"
[x] "In the first cluster from the example, there are 4 data points" -> "In cluster 0 from the example above, there are 4 data points". There is also another mention of "first cluster" a few sentences down, maybe we should always write "cluster 0" so that readers don't mistake it for "cluster 1" instead
[x] "fourth" -> "third" in this sentence at the end of 9.5.2 "we can terminate the algorithm since none of the assignments changed in the fourth iteration"
[ ] The captions of fig 9.9 and 9.12 are not centered (maybe it's consistently like that and I just noticed it here)
[x] number ** 2 -> number**2 (remove spaces)
[ ] James et al ref in 9.8 leads to ch 8 bibliography
number ** 2->number**2(remove spaces)
