Answer:
y = 16
Step-by-step explanation:
Answer:63 I think
Step-by-step explanation:
5 times 8 = 40 113-40=63
Answer:
x= -16/13 y= -41/13 I think
Step-by-step explanation:
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
