Kwan recorded two sets of data. Set 1: 9, 13, 6, 18, 15, 19, 20 Median: 15 Lower Quartile: 9 Upper Quartile: 19 Range: 14 IQR: 10 Set 2: 9, 13, 6, 18, 15, 19, 20, 63 Median: 16.5 Lower Quartile: 11 Upper Quartile: 19.5 Range: 57 IQR: 8.5 One set of data shows an outlier. Which measure of spread was most impacted by the outlier?

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.
