Answer:
Option C.
Step-by-step explanation:
Note: It is given question and option "=" sing is missing. On some places it should be "=" instead of "=".
Consider the given equation is
Using properties of \logarithm we get
![[\because \log_ax=b\Leftightarrow x=a^b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_ax%3Db%5CLeftightarrow%20x%3Da%5Eb%5D)
The solution is x=5.
To check the solution, substitute x=5 in the given equation.
Therefore, x-5 is a true solution because .
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

Answer:
3(4+n) = 12+n is an equation that could be used.
12n = 12+n
11n = 12
n= 1+1/11
