A poll conducted by the Gallup organization asked American adults whether or not they are generally satisfied with their physical attractiveness. One goal of the study was to investigate whether men and women differ with regard to responses on this issue. Identify the explanatory and response variables in this study.

The explanatory variable is, in this case, the gender (men or women) of the person. The study wants to see if gender explains difference on the satisfaction about physical atractiveness.

The response variable will be the proportion that each gender has about this satisfaction. This is the result for which the differences will be tested.

Step-by-step explanation:

The study can be conducted asking to a sample of men and women if they feel satisfied with their physical atractiveness, in a way that the only possible responses are Yes or No.

This allows to get a sample proportion for men and women. In this way, we can later test the hypothesis on the difference between proportions.

With this information we can state the hypothesis and calculate the statistic and the P-value to get some conclusions.

The explanatory variable is, in this case, the gender (men or women) of the person. The study wants to see if gender explains difference on the satisfaction about physical atractiveness.

The response variable will be the proportion that each gender has about this satisfaction. This is the result for which the differences will be tested.

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.
