A biologist is sampling randomly from a population of 1000 birds of which 22-percent are red birds, 18-percent are blue birds, 15-percent are yellow birds, and 14-percent are hawks-

In statistics What is P(third largest yellow bird | yellow bird) and P (red birds | red birds or blue birds)? Give answer in the form of 0.xx

The insertions in red-black trees cost upto 2 rotations (if uncle is black) and upto O(log n) color changes (if uncle is red). Show that amortized color updates per insertion is O(1). (Hint: to develop an appropriate potential function try to see what is decreasing in the structure when we push the red-conflict upwards in case 1.)

There are three loan officers at farmers National Bank. All decisions on mortgage loans are made by one of these officers. The president of the bank would like to be sure that the rejection rate is about the same for the three officers. A sample of 200 recent applications yielded the following results. Is the rejection rate related to the officer that processes the loan? Use the 0.05 significance level.

a. State the null and alternate hypothesis.

H0:____________________

H1:____________________

b. State the decision rule.

c. Compute the value of the test statistic.

d. What is you decision regarding the null hypothesis? Interpret the result.

You may need to use the appropriate technology to answer this question. The International League of Triple-A minor league baseball consists of 14 teams organized into three divisions: North, South, and West. Suppose the following data show the average attendance for the 14 teams in the International League. Also shown are the teams' records; W denotes the number of games won, L denotes the number of games lost, and PCT is the proportion of games played that were won. Team Name Division W L PCT Attendance Buffalo Bisons North 66 77 0.462 8,818 Lehigh Valley IronPigs North 55 89 0.382 8,471 Pawtucket Red Sox North 85 58 0.594 9,095 Rochester Red Wings North 74 70 0.514 6,918 Scranton-Wilkes Barre Yankees North 88 56 0.611 7,144 Syracuse Chiefs North 69 73 0.486 5,764 Charlotte Knights South 63 78 0.447 4,522 Durham Bulls South 74 70 0.514 6,997 Norfolk Tides South 64 78 0.451 6,283 Richmond Braves South 63 78 0.447 4,459 Columbus Clippers West 69 73 0.486 7,791 Indianapolis Indians West 68 76 0.472 8,531 Louisville Bats West 88 56 0.611 9,156 Toledo Mud Hens West 75 69 0.521 8,235 (a) Use α = 0.05 to test for any difference in the mean attendance for the three divisions. State the null and alternative hypotheses. H0: Not all the population means are equal. Ha: μN = μS = μW H0: At least two of the population means are equal. Ha: At least two of the population means are different. H0: μN ≠ μS ≠ μW Ha: μN = μS = μW H0: μN = μS = μW Ha: μN ≠ μS ≠ μW H0: μN = μS = μW Ha: Not all the population means are equal. Correct: Your answer is correct. Find the value of the test statistic. (Round your answer to two decimal places.) 6.95 Correct: Your answer is correct. Find the p-value. (Round your answer to three decimal places.) p-value = .0111 Correct: Your answer is correct. State your conclusion. Do not reject H0. There is sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. Do not reject H0. There is not sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. Reject H0. There is sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. Reject H0. There is not sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. Correct: Your answer is correct. (b) Use Fisher's LSD procedure to determine where the differences occur. Use α = 0.05. Find the value of LSD for each pair of divisions. (Round your answers to two decimal places.) North and South LSD = Incorrect: Your answer is incorrect. North and West LSD = South and West LSD = Find the pairwise absolute difference between sample attendance means for each pair of divisions. (Round your answers to the nearest integer.) xN − xS = 2136 Correct: Your answer is correct. xN − xW = 727 Correct: Your answer is correct. xS − xW = 2863 Correct: Your answer is correct. Which attendance means differ significantly? (Select all that apply.) There is a significant difference in mean attendance between the North division and the South division. There is a significant difference in mean attendance between the North division and the West division. There is a significant difference in mean attendance between the South division and the West division. There are no significant differences. Correct: Your answer is correct.

Based on a study, the average elapsed time between when a user navigates to a website on a mobile device until its main content is available was 14.6 seconds. This is more than a 20% increase from the previous year. Responsiveness is certainly an important feature of any website and is perhaps even more important on a mobile device. What other web design factors need to be considered for a mobile device to make it more user friendly? Among other things, navigation menu placement and amount of text entry required are important on a mobile device. Suppose the following data provide the time (in seconds) it took randomly selected students (two for each factor combination) to perform a prespecified task with the different combinations of navigation menu placement and amount of text entry required.

Use the ANOVA procedure for factorial designs to test for any significant effects resulting from navigation menu position and amount of text entry required. Use

α = 0.05.

(Let factor A be navigation menu position, and let factor B be amount of text entry required.)

Find the value of the test statistic for factor A. (Round your answer to two decimal places.)

Find the p-value for factor A. (Round your answer to three decimal places.)

p-value =

State your conclusion about factor A.

Because the p-value ≤ α = 0.05, factor A is not significant.Because the p-value > α = 0.05, factor A is significant.    Because the p-value ≤ α = 0.05, factor A is significant.Because the p-value > α = 0.05, factor A is not significant.

Find the value of the test statistic for factor B. (Round your answer to two decimal places.)

Find the p-value for factor B. (Round your answer to three decimal places.)

p-value =

State your conclusion about factor B.

Because the p-value ≤ α = 0.05, factor B is not significant.Because the p-value > α = 0.05, factor B is significant.    Because the p-value > α = 0.05, factor B is not significant.Because the p-value ≤ α = 0.05, factor B is significant.

Find the value of the test statistic for the interaction between factors A and B. (Round your answer to two decimal places.)

Find the p-value for the interaction between factors A and B. (Round your answer to three decimal places.)

p-value =

State your conclusion about the interaction between factors A and B.

Because the p-value ≤ α = 0.05, the interaction between factors A and B is not significant.Because the p-value > α = 0.05, the interaction between factors A and B is not significant.    Because the p-value > α = 0.05, the interaction between factors A and B is significant.Because the p-value ≤ α = 0.05, the interaction between factors A and B is significant.

Use this passage to answer the following questions: Climate is gradually changing because of Human activity. Biologists are concerned about the impact of this change on the distribution of biomes across the globe as the change occurs.

a) Briefly describe what is meant by the term climate: (1 or 2 sentences)

b) Briefly explain what a biome is: (1 or 2 sentences)

c) Explain why changing climate will end up changing biome distribution (explain the relationship between climate and biome distribution)

The registrar needs to assign section numbers to a group of 10 sophomores, 20 juniors, and 30 seniors. There are three sections with available seats, say section A, B, C. Each section has room for up to 60 students. We will assume that the registrar randomly and independently assigns the students to the sections.

a) What is the probability that all ten sophomores will be assigned to the same section?

b) What is the probability that exactly 15 students will be assigned to section B?

c) Given that exactly 15 students are assigned to section B, what is the probability that these 15 students are all juniors?

d) Given that exactly 15 students are assigned to section B, what is the probability that these 15 students consist of 5 sophomores, 5 juniors, and 5 seniors?
