Lemons tastes sour to some people. this sourness is inherited through the tas2r38 gene. about 65% of the population has this gene. you want to estimate the proportion of americans who have this gene. how large a sample must you test, with a 2% margin of error and 99% confidence, to estimate the proportion of people who carry the tas2r388 gene?

We are given:

Margin of error

Confidence level = 0.99

We need to find the sample size to estimate the proportion of people who carry the TAS2R388 gene.

The formula for finding the sample size is:

Where:

is the critical value at 0.01 significance level.

Therefore, the required sample size is:

Therefore, the required sample size is 3774

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.
