Well, there is 10 marbles in total and there is 2 black marbles. So, you get 2/10 but you need to simplify it and then you get 1/5.
.123
.456
.002
.1
.2
any of these will work :) hope this helps!
Answer:
Statistically significant means a result is unlikely due to chance. The p-value is the probability of obtaining the difference we saw from a sample (or a larger one) if there really isn't a difference for all users

Therefore, g(-2) = -6
Basically substitute x = -2 in the equation.
