first term(a)=17

common difference (d)=t2-t1

=12-17

=-5

nth term of the arithmetic sequence = a+n×d

=17+n×-5

Concerned about graffiti, mayors of nine suburban communities instituted a citizen community watch program. community monthly in
lesya [120]
The data are reported in the attached table.

We define the null hypothesis H₀ as the statement that is believed true until we prove it wrong with the test.
We define the alternative hypothesis H₁ as the statement we want to conclude with our test.

The difference in graffiti before (B) and after (A) will be:
d = A - B.

If the graffiti declined, it means that A will be smaller than B, therefore d should be negative.

Therefore we can set:
H₀ : μd  ≥ 0
H₁ : μd < 0 

The equal sign would mean that the number of graffiti incidents remained constant, therefore it is part of the null hypothesis.

Therefore the correct answer is B) H₀: μd ≥ 0 versus <span>H₁</span>: μd < 0
