This question has Z parts. Each of the 7 parts (Part A - Part G) has a dropdown list of possible answers. Choose the best answer from the dropdown list for EACH part of the question below. A researcher is interested in whether or not there is any association between normal method of transportation taken to work and reported mood at the beginning of a typical Monday morning. He classifies participants into three transportation groups (those who: bike/walk, take public transit or drive) and asks them how they typically feel on a normal Monday morning: happy/excited, angry/irritated, or sleepy. Data from his survey on 200 participants are presented below. Happy/excited Angry/irritated Sleepy TOTAL Bike/walk 22 6 12 40 Public transit 18 6 36 60 Drive 20 18 62 100 TOTAL 60 30 110 200 You would like to test his question of whether or not there is any association between normal method of transportation taken to work and reported mood at the beginning of a typical Monday morning. Calculate a two variable chi-square test using an alpha (a) level of 0.01.

In a certain butterfly population, a recessive mutant gene has an allele frequency of 0.1 and causes the homozygous larvae to have a more attractive coloration but prone to predation by birds. It has been observed that birds consumed 50% of all the attractively colored larvae compared to 10% predation for dull-colored larvae. a. Identify the type of selection. b. What is the frequency of the mutant gene after one generation of predation? c. If panmictic mating happens after predation, what are the expected frequencies of the larval offspring genotypes?

I. Sketch the figure for the following vector functions. Propose the values for u and v and adjust the graphic to get a good view of the functions. Include the required MatLab code for each graphic. 1) r(u, v) = u cos vi+usin vj + vk 2) r(u, v) = u cos vi + usin vj + sinu k 3) r(u, v) = sin vi + cos u sin 2v j + sin u sin 2v k II. Sketch the vector field for the following vector functions. Consider that -3?x?3 and -3? y ?3. Adjust the graphics to get a good view of the functions. Include the required MatLab code for each graphic. 1) F(x, y) = (cos (x + y), x) 2) F(x,y) = (y,x - y) 3) F(x,y) = (y, y + 2) III. Given the following scalar functions, sketch their gradient vector field. Consider that -4 ? x ? 4 and -4 ? y ? 4. Adjust the graphics to get a good view of the fields. Include the required MatLab code for each graphic. 1) f(x, y) = x(x + y) 2) f(x,y) = (x + y)² 3) f(x, y) = sin\sqrt{x^2 + y^2}
