he mean cost of domestic airfares in the United States rose to an all-time high of $375 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $120. Use Table 1 in Appendix B.

a. What is the probability that a domestic airfare is $555 or more (to 4 decimals)?

b. What is the probability that a domestic airfare is $260 or less (to 4 decimals)?

c. What if the probability that a domestic airfare is between $310 and $500 (to 4 decimals)?

Exercise called: Number Analysis Program

Design a program that asks the user to enter a maximum of 20 numbers. The program should store the numbers in an array and then display the following data:

1-The lowest number in the array.

2-The highest number in the array.

3-The total of the numbers in the array.

4-The average of the numbers in the array.

Acme Materials is a publicly traded company on the NYSE. On October 15, 2021, at 10:46am, company ACME materials, has traded between the price range of $2400 and $2300. Where, $2400 is the high of the range and $2300 is the low of the range.

Fact: As of 10:46am,

- There is a 75% probability that either $2400 will be thehighest price of the day

or

$2300 will be the lowest price of the day.

(Meaning there is a 25% probability that neither 2400 or 2300 will be the high or low of the day.)
Probability of both events occuring together is not provided

Question 1: What is the probability that $2400 is the highest price of the day?

Question 2: Please list / define, what statistical principles and or formula’s make this answer true? How do I get to understandthis answer?

Question 3: I have basic high school math skills, what resourcescan I use to further my understanding of the underlying principles to this solution?

Shaver manufacturing, Inc. offers dental insurance to its employees. A recent study by the Human Resource Director shows the annual cost per employee per year followed the normal distribution, with a mean of $1 280 and the standard deviation of $420 per year. In all questions start with sketching a normal curve. Cross-hatch requested area/probability. If you calculate z-value, round it to two decimal places.

  1. What was the cost for the 15% of employees that incurred the highest dental expense?
  2. What was the range of annual dental costs (in dollars) for middle 80% of all employees?
  3. What is the probability the employee’s annual dental costs are not exceeding $1200?
  4. If random sample of 50 employees is chosen, what is the probability the sample is having a mean of $1100 or more?
  5. If random sample of 95 employees is chosen, what is the probability the sample is having a mean between $1300 and $1400?

Is there a relationship between total team salary and team performance in a sport such as professional basketball? To answer this question we will examine the number of wins and total team payroll in a recent season for all the teams in the National Basketball Association (NBA). The data are in this Excel file.

Question 1. Let the x-variable be the team payroll and let the y-variable be the team wins. Find the intercept b0 and slope b1 of the least squares prediction line Wins^ = b0 + b1*Payroll.
______ intercept (use 2 decimal places in your answer)
______ slope (use 3 decimal places in your answer)

Question 2. If an NBA team spent an additional $8.2 million in team salary, how many more games could the team expect to win? (Use 1 decimal place in your answer).
_______

Question 3. Suppose a basketball team spent $112 million on salaries and won 46 games.
Part a. Based on their payroll would they have done better or worse than predicted? (only 1 submission allowed).
Worse than predicted or better than predicted?

Part b. What is the residual for this basketball team? (use 2 decimal places in your answer)
________

Question 4. All teams have a goal to make the postseason playoffs. A basketball team thinks that it can make the playoffs next year if it wins 7 more games. How much should the basketball team increase its payroll if it wants to make the playoffs next year?

Note: Use 2 decimal places. Your answer should be in units of $1 million; do NOT include a dollar sign in the answer; for example, if a team should increase its payroll by $5,250,000, then the answer is 5.25.
$ ________ increase in team payroll (in $million) needed for basketball team to win 7 more games

2 kilogram of R-134a fills a 0.14-m3 weighted piston–cylinder device at a temperature of –26.4°C. The container is now heated until the temperature is 100°C. Determine the final volume of the R-134a.

An ideal gas (which is is a hypothetical gas that conforms to the laws governing gas behavior) confined to a container with a massless piston at the top. (Figure 2) A massless wire is attached to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 5.40 to 2.70 L . When the external pressure is increased to 2.50 atm, the gas further compresses from 2.70 to 2.16 L .

In a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the ideal gas, decreasing its volume from 5.40 to 2.16 L in one step.

If the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step process in joules?

THE ANSWER IS NOT -101.3!!!!!

An ideal gas (which is is a hypothetical gas that conforms to the laws governing gas behavior) confined to a container with a massless piston at the top. (Figure 2) A massless wire is attached to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 6.40 to 3.20 L . When the external pressure is increased to 2.50 atm, the gas further compresses from 3.20 to 2.56 L . In a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the ideal gas, decreasing its volume from 6.40 to 2.56 L in one step. If the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step process in joules?

An ideal gas (which is is a hypothetical gas that conforms to the laws governing gas behavior) confined to a container with a massless piston at the top. (Figure 2)  A massless wire is attached to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 4.90 to 2.45L . When the external pressure is increased to 2.50 atm, the gas further compresses from 2.45 to 1.96L .

In a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the ideal gas, decreasing its volume from 4.90 to 1.96L in one step.

If the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step process in joules?
