For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. In a random sample of 504 judges, it was found that 281 were introverts. (a) Let p represent the proportion of all judges who are introverts. Find a point estimate for p. (Round your answer to four decimal places.) .5575 (b) Find a 99% confidence interval for p. (Round your answers to two decimal places.) lower limit upper limit Give a brief interpretation of the meaning of the confidence interval you have found. We are 99% confident that the true proportion of judges who are introverts falls outside this interval. We are 1% confident that the true proportion of judges who are introverts falls above this interval. We are 99% confident that the true proportion of judges who are introverts falls within this interval. We are 1% confident that the true proportion of judges who are introverts falls within this interval. (c) Do you think the conditions np > 5 and nq > 5 are satisfied in this problem? Explain why this would be an important consideration. No, the conditions are not satisfied. This is important because it allows us to say that p̂ is approximately normal. Yes, the conditions are satisfied. This is important because it allows us to say that p̂ is approximately normal. Yes, the conditions are satisfied. This is important because it allows us to say that p̂ is approximately binomial. No, the conditions are not satisfied. This is important because it allows us to say that p̂ is approximately binomial.

In humans, brown eye color (B) is dominant to blue eyes color (b) and dark hair color (D) is dominant to blond hair color (d).
1. What is the genotype of a person heterozygous for both traits?
2. What are the possible genotypes of a blue-eye, dark haired individual?
3. What are the possible genotypes of a blue-eye, dark haired individual?
4. What is the genotype of a blue-eyed blond?
5. For an individual who is heterozygous for both traits, what would be the genotypes for the FOUR possible gametes they can produce?
Construct a Punnett square for two parents who are heterozygous for both traits: BbDd x BbDd to do this, place the possible gametes of each parent on the left side and top side, above column and row, and fill in the boxes with the offspring genotypes.
