Adams Airline Company is considering expanding its territory. The company has the opportunity to purchase one of two different used airplanes. The first airplane is expected to cost $14,790,000; it will enable the company to increase its annual cash inflow by $5,100,000 per year. The plane is expected to have a useful life of five years and no salvage value. The second plane costs $34,400,000; it will enable the company to increase annual cash flow by $8,600,000 per year. This plane has an eight-year useful life and a zero salvage value. Required Determine the payback period for each investment alternative and identify the alternative Adams should accept if the decision is based on the payback approach. (Round your answers to 1 decimal place.)

5. FA monomers indirectly interact via covalent bonds with other molecules to form lipid/fat polymers. Explain what this means, and why an additional molecule must be involved. Also describe the interaction that does occurs between FA tails, and why this interaction occurs; compare these interactions in saturated and unsaturated FAs.

I found that sociobiologists suggest that this is nature’s way of successfully preserving the altruistic gene as this is a well adapted characteristic (Leak & Christopher, 1982). How can selfless behavior be deemed a strong adaptation if the species are more concerned with taking care of others over their own well being?

1. What factors are likely to cause a person who comes to the United States from another culture, with different norms for conversational space, to maintain the norms from his or her culture of origin?

​​​​​​The following table shows age distribution and location of a random sample of 166 buffalo in a national park.

Use a chi-square test to determine if age distribution and location are independent at the 0.05 level of significance.

(a) What is the level of significance?


State the null and alternate hypotheses.

H₀: Age distribution and location are not independent.
H₁: Age distribution and location are not independent.H₀: Age distribution and location are independent.
H₁: Age distribution and location are independent.    H₀: Age distribution and location are not independent.
H₁: Age distribution and location are independent.H₀: Age distribution and location are independent.
H₁: Age distribution and location are not independent.

(b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.)


Are all the expected frequencies greater than 5?

YesNo    

What sampling distribution will you use?

uniformchi-square    normalStudent's tbinomial

What are the degrees of freedom?


(c) Find or estimate the P-value of the sample test statistic. (Round your answer to three decimal places.)

p-value > 0.1000.050 < p-value < 0.100    0.025 < p-value < 0.0500.010 < p-value < 0.0250.005 < p-value < 0.010p-value < 0.005

(d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis of independence?

Since the P-value > α, we fail to reject the null hypothesis.Since the P-value > α, we reject the null hypothesis.    Since the P-value ≤ α, we reject the null hypothesis.Since the P-value ≤ α, we fail to reject the null hypothesis.

(e) Interpret your conclusion in the context of the application.

At the 5% level of significance, there is sufficient evidence to conclude that age distribution and location are not independent.At the 5% level of significance, there is insufficient evidence to conclude that age distribution and location are not independent.    

A researcher wishes to estimate the percentage of adults who support abolishing the penny. What size sample should be obtained if he wishes the estimate to be within 5 percentage points with 95​% confidence if ​(a) he uses a previous estimate of 22​%? ​(b) he does not use any prior​ estimates? Round up the answer to the nearest integer

Implement a simple football league system that will record and display the league according to the following specification: Each Team will have the following attributes: • Name • Games played • Games won • Games lost • Games drawn (this should be a calculated value) • Points (calculate using 3 points for a win and 1 for a draw)

Your program must include the following functionality:

• The ability to enter a team’s results from the keyboard.
• All records entered must be written to a text file.
• The system must allow new records to be added to the end of the file.
• An option to read the file and display the information on the screen should be given.
• Your program should run all the above functions without shutting down.
• You can include any additional functionality that you consider would make the program more useful or user friendly.

(a) At what temperature do the Fahrenheit and Celsius scales have the same numerical value? (b) The Fahrenheit and Kelvin scales? (c) Describe the basis of each of these three temperature scales. The two cryogenic liquids I use in the lab are liquid nitrogen and liquid helium. What are the boiling points of those two liquids (e) in Fahrenheit? (f) in Kelvins?
