Assignment 2 - Part d - mismatch in instructions

[docjason]

Assignment materials in github does NOT match the online posted instructions for Data Manipulation course.

Online instructions
https://www.coursera.org/learn/data-manipulation/programming/AxbQn/twitter-sentiment-analysis

(d) count: Write a SQL statement to count the number of unique documents containing the word "law" or containing the word "legal" (If a document contains both law and legal, it should only be counted once)

github instructions:

https://github.com/uwescience/datasci_course_materials

datasci_course_materials/assignment2.html

(d) count: Write a SQL statement to count the number of documents containing the word "parliament"

The grader is looking for counts of law/legal not parliament. Therefore, online instructions are the ones to use if there is a discrepency.

Also typo in Problem 2

Part (g) matrix shows 0 0 -3 but the matrix is showing row at 2,2,-3.
