The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds. From the data, we can conclude that the number of men weighing more than 165 pounds is beyond the mean weight of 1000 men and the number of men weighing less than 135 pounds is less than the mean weight of 1000 men.

The correct statement regarding the operations with polynomials is given as follows:
C. (10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 11x² + 2x - 13.
Like terms are terms that share these two features:
If two terms are like terms, then they can be either added or subtracted, that is, we can use them to simplify a polynomial.
Hence the polynomial that is correctly simplified in this problem is given as follows:
(10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 2x² + 9x² + 2x - 11 - 3 = 10x³ + 11x² + 2x - 13.
Meaning that option C is the correct option in the context of this problem.
