Why is the point (4, 3) there but not mentioned??
Anyways, the point that P (3, 0) is after rotating 180° about the origin is (-3, 0).
btw, for 180 rotations about O, just take negative value of (x, y)--> (-x, -y)
That way -(3), -(0) becomes (-3, 0)

N = 2424 is the sample size (amount of cars being sampled)
df = degrees of freedom
df = n-1
df = 2424-1
df = 2423

Side Note: if there is a typo and the sample size should be n = 24 (instead of 2424), then the df would be df = n-1=24-1 = 23
