Hi, hope this helps, so the sum is 10+12+(-27)+(-9)+10
Then -10 + 12 - 27 - 9 + 10= -54 + 20= 26
So the answer is -26
The critical values of z= -2.575 and z= 2.575
the formula z= x bar- u/sigma / square root of n
but in general, we state a hypothesis.
then compare the results to determine which hypothesis is most likely
you seem to have the right idea that its a 2 tailed test of equality.
± 2.575 = x− μ σ / √n
CI : x ± 2.575 (σ/√n) = μ
