4.In dancing bears, short fur is dominant to long fur, and curly hair is dominant to straight. The genes for these traits are located on separate autosomes.

You have a large population of dancing bears with the following allele frequencies

Short fur (S) p = 0.5, Long fur (s) q = 0.5

Curly hair (C) p = 0.3, Straight hair (c) q = 0.7

You allow the population to randomly breed for several generations. You have a population of 1000 dancing bears and count 510 with curly hair.

Is this population in Hardy-Weinberg equilibrium for this trait based on the starting allele frequencies?

Multiple Choice

a.No, that is not enough with curly hair.

b.No, that is too many with curly hair.

c.Yes.

6.A species of plant that grows on rock outcrops produces a chemical on its stigmas that prevents pollen germination. After collecting pollen over the course of a day, the chemical wears off and all the pollen grains germinate at once with the fastest growing male fertilizing all or most of the eggs in the ovary.

You conduct an experiment where you mix equal amounts of pollen from three different plants and place it on the stigmas of three separate flowers on six different plants. You count the number of seeds produced by each flower and use genetic tests to determine paternity of the seeds.

You think that the same male plant will fertilize the most seeds on all of the female plants. If so, this is an example of disruptive selection.

Multiple Choice

a.True.

b.False.

A hotel has 210 units. All rooms are occupied when the hotel charges ​$90 per day for a room. For every increase of x dollars in the daily room​ rate, there are x rooms vacant. Each occupied room costs $ 36 per day to service and maintain. What should the hotel charge per day in order to maximize daily​ profit?

Suppose 1% of the population of Toronto has been infected with SARS-CoV-2 at some point (call the corresponding proportion, 0.01, the prevalence of the virus). There are now antibody tests available for SARS-CoV-2 to detect whether someone has ever been infected. However, like any test, these tests are not perfect and are subject to error at some rate.

Also suppose that, when someone has been infected, the test correctly comes up positive 98% of the time, comes up negative 1.7% of the time, and comes up inconclusive in the remaining 0.3% of cases. Also suppose that when someone has not been infected, the test correctly comes up negative 99% of the time, positive 0.8% of the time, and inconclusive 0.2% of the time.

Let ?D be the event that a randomly selected person in Toronto has truly been infected (?D for disease). Thus, ??Dc is the event that the person has never been infected. Let ++ be the event that a test comes up positive, and – the event it comes up negative. Use ?O for inconclusive.

Draw a probability tree to depict the relationship between these events (see Lecture 7). Use the tree to compute ?(?|+)P(D|+), the probability that someone has been infected conditional on getting a positive test result. What does this result mean in words and why might it be surprising (1-2 sentences)?

Use the same information about testing for SARS-CoV-2 as above. What happens if prevalence changes to 0.10? Redraw the tree, and compute ?(?|+) again using this new prevalence. What do these results suggest about the importance of prevalence in interpreting test results like this (1 sentence)? Suppose a random person in Toronto gets an inconclusive result on an antibody test for SARS-CoV-2. Is the probability that they are infected lower or higher than it was before we knew their test result? Use your tree to explain.

TechMedia, Inc. is a U.S. firm that is planning to build a new production facility in either the USA or China. The initial cost to build the facility will be $8.2 million if built in the USA or ¥45 million if built in China. In either location, the project will require an initial investment of $225,000 in net working capital. Net working capital at the end of each of years 1 through 4 will be $65,000. Net working capital will be $0 at the end of the fifth (final) year of the project. The current exchange rate between the two currencies is 6.75 ¥/$. The risk-free rate in the U.S. is 0.8% and the risk-free rate in China is 6.1%. TechMedia, Inc. pays a 35% tax rate on its taxable income. The firm’s current and target debt-equity ratio is 0.6. Its cost of debt is 6.5% and its cost of equity is 11.5%. The facility will be fully depreciated over five years (straight line) with no salvage value. The facility is expected to impact the firm’s operating revenues and expenses as shown below. USA Location China Location Year Additional Revenue ($) Additional Expense ($) Additional Revenue (¥) Additional Expense (¥) 1 $4,000,000 $1,500,000 ¥20,000,000 ¥7,000,000 2 $4,000,000 $1,500,000 ¥25,000,000 ¥8,000,000 3 $5,000,000 $1,750,000 ¥30,000,000 ¥9,000,000 4 $6,500,000 $2,000,000 ¥35,000,000 ¥9,000,000 5 $6,500,000 $2,000,000 ¥40,000,000 ¥8,000,000 Which location, if either, should TechMedia, Inc. choose?

(b) Find the correlation coefficient. (Round your answer to 3 decimal places. A negative value should be indicated by a minus sign.)

r              

(c-1) To test the correlation coefficient for significance at α = 0.025, fill in the following. (Use the rounded value of the correlation coefficient from part b in all calculations. For final answers, round t_calc to 3 decimal places and the p-value to 4 decimal places. Negative values should be indicated by a minus sign.)

On any given day, a bike shop sells either 0, 1, 2, or 3, bikes, with probabilities 0.3, 0.4, 0.2, and 0.1 respectively.

Suppose they make a profit of $400 from each bike sold, but they have a fixed cost of $400 per day for rent and salaries at the small dealer.

Let the random variable X = the net profit per day. (i.e., the profit from the sale of bicycles minus the fixed cost).

a) Develop a probability distribution for the net profit per day. What are the X and f(x) values?

b) Show that your probability distribution satisfies the conditions for a discrete probability distribution. In other words, describe in words why the probability distribution that you created is a valid one.

c) Calculate the expected value of the probability distribution. Interpret what this means in words.
