Explanation:

Step1: Find the sum of the numbers

$-5.436+( - 5.388)+(-5.425)+(-5.410)+(-5.424)+(-5.424)+(-5.407)+(-5.430)=-(5.436 + 5.388+5.425+5.410+5.424+5.424+5.407+5.430)=-43.344$

Step2: Divide by the number of values

There are 8 values. So, the mean is $\frac{-43.344}{8}=-5.418$

Step3: Round to the nearest tenth

$-5.418\approx - 5.4$

Answer:
