Answer:
x = 162
Step-by-step explanation:
The equation editor lets you properly write exponents, so we have to assume that your equation is supposed to be equivalent to ...
27 = x/6
27·6 = x = 162 . . . . multiply by 6
_____
On the off chance you intend ...
you can solve this by taking logarithms and dividing by the coefficient of x. Using base 3 for the logarithm may be easiest.
This version of the equation has solution x = -6.
Just to be clear, the data are reported in the picture attached.
We set the difference in graffiti incidents between before (B) and after (A) as:
d = A - B
If the number of incidents has indeed reduced, then d will be negative.
In order to choose the hypothesis, we need to recall that the null hypothesis H₀ represents the statement that we want to prove wrong, while the alternative hypothesis H₁ represents the statement that we want to prove right.
Therefore, we want μd to be strictly negative (= 0 would mean that the number of incidents stayed constant).
Hence:
H₀ : μd ≥ 0H₁ : μd < 0
