You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If​ convenient, use technology to construct the confidence intervals.

A random sample of 35 home theater systems has a mean price of ​$144.00. Assume the population standard deviation is $15.90.

A. Construct a 90% confidence interval for the population mean.

The 90% confidence interval is (__,__)

In Python

Suppose there is a movie theater who charges ticket based on ages. Less than 3 years old, free; between 3 to 12, $10; more than 12 years old, $15. Please design a program with loop to,

1) Ask the name then age of the audience,

2) Based on audience's input, tell the audience (with the person's name) how much is the ticket,

3) Stop the program when type in 'quit' in your program.

You are considering opening a drive-in movie theater and running it for ten years. You have spent after-tax $10,000 researching the land that will be used for theater, but if you take the project you expect to incur another immediate after-tax expense of $20,000 as you work with a consulting firm to decide how to most efficiently run the business.

The project entails an immediate $100,000 capital expenditure, which can be depreciated over 10 years. You expect to sell this capital investment for $25,000 at the end of the ten year project. Working capital expenses for the project are $50,000 immediately, $40,000 incurred two years from today, both of which are fully recovered in ten years (at the end of the project).

The project’s operating costs are expected to be $100,000 for each of the first five years and then (starting between t=5 and t=6) grow at -5% per year through the end of the project (i.e., through t=10). You expect the project’s revenues to start at $100,000 starting one year from today and remain constant for the life of the project.

  1. ) You decide to use 10% as the project’s opportunity cost of capital. Your expected tax rate is 25%. What is the project’s NPV?

Sophie Bradford is the manager of Anthem's traditional Sunday​ Flicks, sponsored by the Anthem Student Association....

Sophie Bradford is the manager of Anthem's traditional Sunday​ Flicks, sponsored by the Anthem Student Association. The admission price is deliberately set at a very low $ 3.5. Each​ Sunday, a film has two showings and a maximum of 1,600 tickets can be sold for each showing. The rental of the auditorium is $ 280 and labor is $455​,including $120 for Bradford.Bradford must pay the film distributor a​ guarantee, ranging from $ 270 to $ 800, or 40% of gross admission​ receipts, whichever is higher. Before and during the​ show, she sells​ refreshments; these sales average 10% of gross admission receipts and yield a contribution margin of 50 %.

Requirement 1: On June 3, Bradford screened The Descendants. The film grossed $10,500. The guarantee to the distributor was $700 or 40% of gross admission receipts, whichever is larger. What operating income was produced for the student association.

Requirement 2: Recompute the results if the film grossed $1,400

Requirement 3: The​ "four-wall" concept is increasingly being adopted by movie producers. In this​ plan, the​ movie's producer pays a guaranteed fixed rental to the theater owner​ for, say, a​ week's showing of a movie and the producer receives the ticket receipts less the fixed rental. As a theater​ owner, how would you evaluate a​ "four-wall" offer?

1. Compare and contrast the fields of clinical psychology and counseling psychology. Describe each specialization. In what ways are they similar? In what ways do they differ? Include three similarities and three differences in your answer.

2. When psychologists conduct scientific studies, they have one of three goals: to describe, to correlate, or to experiment. Describe each goal, including how they differ from one another.

3. You're sitting in the theater watching a movie when the fire alarm goes off. You jump and get out of your seat to leave the theater, but the alarm stops and an announcement is made that the alarm was unintentional and there is no emergency. You calm down and go back to enjoying your movie.

Name and explain the roles of the divisions of the autonomic nervous system in your responses.

4. Explain two ways in which the left and right hemispheres of the cerebrum differ in function.

5. Define and differentiate between sensation and perception. Use an example to illustrate your descriptions. Be sure to use the term that describes the conversion of environmental energy into neural signals.

6. Define and differentiate between bottom-up and top-down processing. Give an example of each in a single sensory experience.
