Mistake in statistics exercise 2.13

I'm finding that I like your courses overall, but your exercises/solutions files need more quality control. For example in exercise 2.13, task 3, I'm asked to use data on all apartments (there are also offices in the data). However when I went to check my work in the solutions file, suddenly the task wording is "all properties" and the solution result seems to include offices as well as apartments. So my work does not align with the solution, and I have to more manually confirm that this is only because of this discrepancy, to make sure I didn't also miss something. Sorry I can't remember other examples, but I've seen similar things in at least 3 previous exercises (one I already contacted you about at least).
