2020 + <em>N</em> ≡ 0 (mod 11)
<em>N</em> ≡ -2020 (mod 11)
Notice that 2020 = 183 • 11 + 7, so
<em>N</em> ≡ -(183 • 11 + 7) (mod 11)
<em>N</em> ≡ -7 (mod 11)
<em>N</em> ≡ 4 (mod 11)
Well, it is a binomial variable as long as you limit the amount of people you ask to a certain number for every trial.
Also, you MUST record the data either as they choose Frigidaire or they didn't choose Frigidaire. It MUST be these two choices, or it isn't binomial.
