What we can say with a good deal of certainty is that our sample is biased towards the higher spectrum and that the real value of the mean for our population is lower than the obtained value of our sample. If this is true, we should expect for the standard deviation to be higher than in the population.
The answer is -13. You figure it out by multiplying 2.5×-5.2=13
Multiply: (3x-4)(2x-5)
This comes out to 6x^2 - 15x - 8x + 20
Combine the x terms and you'll be done.
