Let’s model the inheritance of a genetic trait, for example eye color. Every individual has a pair of chromosomes for eye color, and an offspring gets one chromosome from each parent. Say a represents a brown-eye gene, and b represents a blue-eye gene, and that brown is dominant (meaning the eye will be brown if the individual carries at least one a gene, and only bb pair will result in blue eyes). The order in the pair does not matter. We also know that throughout the population, the probability that a randomly chosen eye-color gene is a is given by p (so P{b} = 1 − p), and that mate selection is independent of eye color. How can we model the gene passage from a parent to a child using Markov Chain? Please specify states and transition probabilities.

according to the US census bureau, the population of the US seniors65 and older, in the year 2004 was approximately 36,300,000 people. In the year 2010, it was 40,267,984 people. the senior population was growing at an approximately constant rate during this period.
(a)use this information to express the US senior population as a function of time since the year 2000.
(b) what is slope of your function? what does this mean in the context?
(c) what would this model indicate that the US population of seniors was in the year 2000? ( The actual population in that year was approximately 34,991,753)
(d) what does this model predict the US population of seniors to be for the 2020 census? Do you think this will be an overestimate or underestimate and why?
(e) when does your model predict the US population of senior to be 45,500,000 people?

Assuming you are dealing with a finite statistical population of lemmings, whose parametric mean is estimated at 63.5 g and the parametric variance at 148.84 g2.
4. What would be the probability of randomly selecting, in this population, individuals weighing less than 41.0 g? 5. What would be the probability of randomly selecting, in this population, an individual whose weight would be between 60.0 and 70.0 g?
6. What is the probability, still in this population, that an individual weighs between 50.0 and 60.0 g? 7. What would be the standard deviation of the average of all possible samples of 10 elements taken from this population?

A random sample of n = 500 observations from a binomial population produced x = 250 successes. Find a 90% confidence interval for p. (Round your answers to three decimal places.)
Interpret the interval:
A. In repeated sampling, 90% of all intervals constructed in this manner will enclose the population proportion.
B. 90% of all values will fall within the interval.
C. In repeated sampling, 10% of all intervals constructed in this manner will enclose the population proportion.
D. There is a 10% chance that an individual sample proportion will fall within the interval.
E. There is a 90% chance that an individual sample proportion will fall within the interval.

1. The substitution effect of a price increase:
A. the consumer to purchase less of the good that is now relatively more expensive.
B. causes the consumer to purchase more of the good whose price has risen.
C. can cause the consumer to purchase either more or less of the good.
D. has no effect on the amount purchased of either good.
2. Income Effect refers to
A.change in consumption choices resulting from a change in relative prices
B.change in consumption choices resulting from a change in purchasing power
C. change in consumer's preference
D. an change in happiness when you get a raise

A.parallel to the new budget constraint
B.but tangent to the old indifference curve
C.parallel to the new budget constraint, but tangent to the old indifference curve
D. parallel to the new budget constraint, tangent to the old indifference curve, and below the new indifference curve

In 2020, Carson is claimed as a dependent on his parent's tax return. His parents report taxable income of $200,000 (married filing jointly). Carson's parents provided most of his support. What is Carson's tax liability for the year in each of the following alternative circumstances? Use Tax Rate Schedule, Tax Rates for Net Capital Gains and Qualified Dividends for reference.
a. Carson is 17 years old at year-end and earned $14,000 from his summer job and part-time job after school. This was his only source of income.
b. Carson is 23 years old at year-end. He is a full-time student and earned $14,000 from his summer internship and part-time job. He also received $5,000 of qualified dividend income. (Do not round intermediate calculations. Round your answer to 2 decimal places.)
It is a tax question.
