Given that Set X: {-27, -20, -13, -6, 1, 8, 15} and Set Y: {-23, -19, -15, -11, -7, -3, 1, 5, 9, 13} and we need to find the mean of Set X and Set Y

============================================================

Theory

‣‣‣ Mean = (Sum Of All The Numbers) / (Total Number Of Numbers).

============================================================

Quantity A: Mean of Set X

Mean of Set X = \(\frac{-27 + (-20) + (-13) + (-6) + 1 + 8 + 15}{7}\) = \(\frac{-42}{7}\) = -6

Quantity B: Mean of Set Y

Mean of Set Y = \(\frac{(-23) + (-19) + (-15) + (-11) + (-7) + (-3) + 1 + 5 + 9 + 13}{10}\) = \(\frac{-50}{10}\) = -5

Clearly, Quantity B(-5) > Quantity A(-6)

So, Answer will be B.
Hope it helps!
