Which of the following is true of probability sample sizes? the shorter the variability in the data being estimated, the larger the sample size needed the higher the level of confidence desired, the smaller the sample size needed the population standard deviation is a measure of the dispersion of the population, and its square root is referred to as the population variance the smaller the desired error, the smaller the sample size the more precise the required sample results, the larger the sample size

b. 13

step-by-step explanation:

as there are 13 students in bowling class therefore the most reasonable answer is b as only 13 students are in the bowling class.

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.

no one knows lol
