What is the rank correlation coefficient?  (Round to three decimal places.)

What is the critical rho value at a 0.01 significance?

Do we have correlation?

  • No, the rank correlation coefficient is larger (in absolute value) than the critical rho value.
  • No, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
  • Yes, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
  • Yes, the rank correlation coefficient is larger (in absolute value) than the critical rho value.

1) Why would the anterior portion of the nose be cartilage instead of bone?

2) Some elderly patients have difficulty swallowing and closing their epiglottis. Would this cause any potential problems in the respiratory system?

3) What are the two things shown or implied in slide 26 that work together for a particular goal? What is their purpose? If either is not performing, would performance be compromised?

4) Slide 40 shows emphysema reducing the total surface area of the alveoli. Where else have we seen surface area being important in A&P?

5) OPTIONAL Draw two close segments of the lung (schematically) and draw why infections going from one to another are somewhat inhibited because of the anatomy. Draw the same two area but without being contained in segments and draw why an infection can go more easily from one of the regions to the other region.

6) Referring to the oxygen-hemoglobin dissociation curve (slide 76), would a healthy patient benefit from breathing in a higher percentage of O2 such as when visiting an “oxygen bar”. Would there potentially be any benefit via a different route than hemoglobin (but isn’t)?

7) Relate the three factors affecting the affinity of Hb for O2 on slide 77, to exercise. Does each have any connection to exercise?

8) Since a person always needs oxygen, why would the bronchioles have the ability to contract at all? Why would the trachea not have that ability?

Step 1:Find the pair with the smallest distance.

Step 2:Join them in one group and draw those branches.

Step 3:Compute average distance between this group and all other taxa one-by-one and create new table with those values.

Step 4:Repeat Steps 1 to 3 using the new distance matrix.

Based on above data, find the first two characters with the shortest distance and draw those branches with the respective distances on the branches below according to the example given in class or online. This should be your first two branch tips.

C and D is the pair with the shortest distance as it is 2 units. A sub tree will be drawn with the branch point half way between the two given units. Each branch is 1 unit as this is 2 units divided equally and each point is 1 unit away from the center node.

Recalculate distances based on the combination of the last characters. This first table has been partially filled out for you. Determine and enter the missing values. (You need not fill out the boxes above the dashes as they are mirror values to the below-dash values.)

You have been hired as a financial advisor to Red Sox DH J. D. Martinez who plans to opt-out of the final 3 years and $62 million of his contract. He has received two offers, one from the Chicago White Sox for 5 years and $130 million and one from the Texas Rangers also for 5 years and $130 million and wants to select the best offer. The White Sox’s offer will pay J.D. $20 million in year 1, $20 million in year 2, and 30 million per year for years 3 through 5. The Ranger’s offer will pay J.D. $35 million in year 1, $35 million in year 2, $30 million in year 3, and $15 million per year in years 4 and 5. If the appropriate discount rate is 7.5%, which offer will you advise J.D. to choose?

Consider the set of integer numbers from 0 to 9, that is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. Bob wishes to use these numbers to create a 7-digit password to secure his new laptop. Note that each number can appear in any position (for example, 0 can be the first number in the password). (a) Find the number of 7-digit passwords that are possible. (b) Find the number of 7-digit passwords with distinct digits. (c) Find the number of 7-digit passwords that contain exactly three 4s (that is, inside the password the number 4 appears exactly three times). (d) Find the number of 7-digit passwords that do not contain any 1 (that is, inside the password the number 1 never appears). (e) Find the number of 7-digit passwords that contain at least one 6 (that is, inside the password the number 6 appears at least once). (f) Find the number of 7-digit passwords that contain exactly two 6s and one 5 (that is, inside the password the number 6 appears exactly twice and the number 5 appears exactly once). (g) Find the number of 7-digit passwords that contain exactly two 4s and three 2s (that is, inside the password the number 4 appears exactly twice and the number 2 appears exactly three times).

Sanders Enterprises, Inc., has been considering the purchase of a new manufacturing facility for $284,000. The facility is to be fully depreciated on a straight-line basis over seven years. It is expected to have no resale value after the seven years. Operating revenues from the facility are expected to be $119,000, in nominal terms, at the end of the first year. The revenues are expected to increase at the inflation rate of 4 percent. Production costs at the end of the first year will be $44,000, in nominal terms, and they are expected to increase at 5 percent per year. The real discount rate is 7 percent. The corporate tax rate is 40 percent.
