You want to estimate the percent of Democrats that will vote for Biden in the upcoming presidential election. You take a SRS of 50 Democrats and find that 42 of them plan to vote for Biden.

Answer the following: a) Determine the population(s) and parameter(s) being discussed. Remember, population is the group we are wondering about and parameter is a value that describes the whole group, like a mean. b) Determine which tool will help us find what we need (one sample z test, one sample t test, two sample t test, one proportion test, one sample z interval, one sample t interval, two sample t interval, one proportion interval) c) Check if the conditions for this tool hold. d) Whether or not the conditions hold, use the tool you chose in part (b). Use C=95% for all confidence intervals and α = 5% for all significance tests. ** Be sure that all methods end with a sentence describing the results. **

You review EPIC for Mr. Smith and find that he was admitted to the hospital last night with the diagnosis of bleeding esophageal varices. He is 38 years old, 6’ tall, and weighs 155 lbs. He has a history of alcohol abuse and bipolar disorder. He is on bedrest with bathroom privileges, NPO, and has an IV with lactated ringers running at 125mL/hr. He is a bit confused and has been shivering. His temp is 100.6° F. He is scheduled for a variceal ligation.

Medications: IV octreotide 50 mcg/hr x 3 days

Thiamin 100 mg PO every morning

MVI tablet each morning

Propranolol 20 mg PO BID

Lithium 900 mg PO each morning

Labs:

Alanine aminotransferase (ALT) – 80 Units/L

Aspartate aminotransferase (AST) – 250 Units/L

Hgb 6.8 Hct 21 Potassium – 3.3 mEq/L

Folate – 3 nmol/L (7-36 nmol/L)

Thiamine – 55 nmol/L (70-180nmol/L)

Vit B12 – 100 ng/L (130-700 ng/L)

1. The patient has a Ringers Lactate IV hanging – is this compatible with octreotide IV piggyback?

2. What vital signs would be important to monitor for this patient?

3. Consider the history of alcohol abuse.  What are possible causes for confusion and shivering for this patient?

4. Discuss the use of a Clinical Institute Withdrawal Assessment (CIWA) scale. Your patient has a score of 12 on the CIWA scale.  

1. 58. Issuance, Splits and Dividends
2. Suppose AT7 T had originally issued 200 million shares of common stock, $1 par, for $15 cash per share many years ago. Prepare the journal entry

2. Suppose AT&T had retained earnings of $5 billion by December 3 1, 20X2. The board directors declared a two-for-one stock split and immediately exchanged two $.50 par shares for each share outstanding. Prepare the journal entry, if any. Present the stockholders’ equity each share outstanding. Prepare the journal entry, if any* Present the stockholders’ equity section of the balance sheet before and after the split.

3. Repeat requirement 2, but assume that one additional $j par share was issued by AT&T for each share outstanding (instead of exchanging shares) and accounted for as a two-for-one sock split “effected in the form of a stock dividend.”
4. What journal entries would be made by the investor who bought 1,000 shares of AT&T common sock and held this investment throughout the time covered in requirements 1,2, and 3?

On a trip to Mars, you discover a new lifeform, which you name quinks. You decide to look at the genetics behind both body shape and fur color of the quinks. You start with two true-breeding quinks. Galax is a square, purple quink. Nova is a round, green quink. All of the baby quinks from Galax and Nova are square shaped with green fur. Note, questions 1-8 below are all connected to each other.

1. Based on the information provided above, what alleles are dominant?

2. Based on the information provided in the introduction paragraph, what are the genotypes of the F1 offspring of Galax and Nova? Your answer must include the ratio of these genotypes. Make sure that you define the symbols you use for your alleles.

3. During your study, one of the F1 baby quinks from question 2 (you name him Jet) falls in love with a true-breeding round shaped, purple quink named Terra. Jet and Terra shortly have babies of their own (quinks grow up quickly!) What are the genotypes of the offspring of Jet and Terra? Your answer must include the ratio of these genotypes. Make sure that you define the symbols you use for your alleles.

4. What are the phenotypes of the offspring of Jet and Terra from question 3? Your answer must include the ratio of these phenotypes.

5. Your astronaut coworker Buzz wants to do a test cross with one of the square shaped quink babies of Jet and Terra from question 3/4. Buzz calls this square-shaped quink Helio. Why might Buzz want to do this test cross?

6. For this test cross in question 5, you have four quinks to pick from, listed below. Which one do you use to mate with Helio for the test cross? (Pick one)

a. A quink named Orbit with a square body shape (homozygous)

b. A quink named Sunspot with a round body shape (homozygous)

c. A quink named Lumi with a square body shape (heterozygous)

d. A quink named Aerial with a round body shape (heterozygous)

7. You loved your trip to Mars so much, that you went back to further study quinks. On your second trip, you find a quink that has orange fur named Orion. You cross Orion with Nova (true-breeding green quink, from the opening paragraph) and get 50% green and 50% spotted (both orange and green spots) quinks. What is a possible explanation for this? You must support your answer using genetic details.

8. What is the genotype of Orion from question 7? Make sure that you define the symbols you use for your alleles.

A GC needs to fill and compact a trench that has the following dimensions 150 x 50 x 1.5 ft.   The sub is going to use a dump truck that can carry 12 CY, and travels at an average speed of 40 mph. The borrow pit is located 45 miles from the construction site. The truck driver makes $50/hr and works 8 hours per day. Loading time for the truck is 30 minutes and unloading time is 5 minutes. The sub has to rent the truck at $500 per day + a driver @ $50/hour. The cost of soil $20 per BCY. The soil has a swell factor of 18% and a compaction factor of 12%.

How much will the driver cost?

A shell and tube type of heat exchanger with one shell pass and two tube passes will be designed to provide the given heat transfer rate Q(kW) to cool hot water by using cold river water . The hot water flows through the shell and the cold water flows through the tubes. The inlet and outlet temperatures of the hot water and the cold water are given as Thi, The and Tci, Tce in degrees Celcius. Design the shell and tube heat exchanger by making necessary assumptions to calculate the dimensions of the heat exchanger. Q= 10 KW Hot Fluid( Water) Thi= 70 Celcius The= 40 Celcius Cold Fluid ( Water) Tci= 5 Celcius Tce= 15 Celcius 1) Assume the tube diameter and tube length . 2) Assume fouling coefficient based on inside and outside tubes, hdi and hdo . 3) Select the material of construction for the tubes to determine the thermal coefficient. 4) Find the Log Mean Temperature Difference (LMTD) . 5) Obtain the Correction Factor F. 6) Calculate the Mean Temperature Difference. 7) Assume the Overall Heat Transfer Coefficient “U” as initial guess according to type of heat exchanger. 8) Calculate the provisional area. 9) Calculate the number of tubes based on the assumed tube diameter, thickness of the pipe and tube length L. 10) Calculate the tube pitch and bundle diameter.
