Arandom sample of 205 college students was asked if they believe that places could be haunted, and 65 responded yes. estimate the true proportion of college students who believe in the possibility of haunted places with 99 % confidence.

The 99% confidence interval is given below:

Where:

is the critical value at 0.01 significance level

        rounded to two decimal places

Therefore, the estimate of the true proportion of college students who believe in the possibility of haunted places with 99% confidence is (0.23,0.40).          

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
