Answer:
3
Step-by-step explanation:
Standard derivation is how much the data varies from the mean
class 2 has a lower derivation, the scores vary less from the mean, being closer
Y = -2x + 4
Therefore, gradient = -2
(-3,9)
y = m(x - x1) + y1
y = -2(x - (-3)) + 9
y = -2(x + 3) + 9
y = -2x - 6 + 9
y + 2x = 3
$50 = $625 (r)(4), so r = 50 / (4*625) = 0.02. This is 2% annually.
