Write and run a SQL query to determine which airport in the fly.airports table is closest to the geographical (not magnetic) North Pole, using the following calculation for the distance in kilometers, using the latitude (lat) column: distance = 6371 * 2 * asin(least(1, sin(radians(90 – lat) / 2))) (Note: The least function chooses the minimum value among two or more scalar values—similar to the MIN function, but MIN works on values in a column.) Which airport is closest to the geographical North Pole?

A student, Samuel, speculates that exam scores may be linearly related to hours spent studying. Samuel collects five data points, (X,Y), where X represents hours studied and Y represents exam score — Ricardo: (2,45); Janette: (4,80); Calvin: (7,95), Edith: (3,55); Joachim: (1,30). The mean score is 61. Samuel uses the equation Y=20XY=20X to represent the data. Calculate the R-squared value of this line. Assuming that an R-squared value less than 0.4 is “poor”, a value between 0.4 and 0.8 is “fair”, and a value above 0.8 is “good”, how well does this line Y=20X represent the data?
