The restaurant maintains the catalog for the list of food and beverage items that it provides. Apart from providing food facility at their own premises, the restaurant takes orders online through their site. Orders on the phone are also entertained. To deliver the orders, we have delivery boys. Each delivery boy is assigned to the specific area code. The delivery boy cannot deliver outside the area which is not assigned to the delivery boy (for every delivery boy there can be a single area assigned to that delivery boy). The customer record is maintained so that premium customer can be awarded discounts.

Need copy of code and a report if possible.

Code is Python.

Instructions from Professor:

1. What will you be looking for in a political candidate the next time you vote, in terms of economic philosophy and economic policies? What have you learned so far that has influenced your position? Have any of your ideas changed? Your essay should be at least 200 words.

There are a number of steps involved in testing hypotheses. The mechanics of testing a hypothesis are not difficult, but the underlying logic requires quite a bit more explanation. In this activity, you will start by working through the steps of hypothesis testing to give you some experience with the process. Then, you will work through the steps for that same problem in far more detail. Finally, there is some logic that is inherent in the process of hypothesis testing that is not obvious in the steps but is vitally important to your understanding. The last part of this activity explains that logic. Let’s start with an example: Suppose you are an educational researcher who wants to increase the science test scores of high school students. Based on tremendous amounts of previous research, you know that the national average test score for all senior high school students in the United States is 50 with a standard deviation of 20. In other words, 50 and 20 are the known population parameters for the mean and the standard deviation, respectively (i.e., µ = 50, σ = 20). You also know that this population of test scores has a normal shape. You and your research team take a sample of 16 high school seniors (N = 16), help them for 2 months, and then give them the national science test to determine if their test scores after help were higher than the national average science test score of 50 (i.e., µ = 50). After the help, the mean test score of the 16 student sample was M = 61 (SD = 21). Now you need to determine if the difference between the sample’s mean of 61 and the population mean of 50 is likely to be due to sampling error or if the help improved the sample’s science test score. Because you are only interested in adopting the help program if it increases science test scores, you use a one-tailed hypothesis test. You also chose a .05 alpha value (i.e., α = .05) as the decision criterion for your significance test. If the sample mean has a chance probability less than .05, you will conclude that the help program improved students’ test scores.

2. Write H0 next to the symbolic notation for the null hypothesis and H1 next to the research hypothesis.

______µhelp > 50 ______µhelp < 50 ______µhelp ≥ 50 ______µhelp ≤ 50 ______µhelp > 61 ______µhelp < 61 ______µhelp ≥ 61 ______µhelp ≤ 61

3. Write H0 next to the verbal description of the null hypothesis and H1 next to the research hypothesis.

_____The population of students who receive help will have a mean science test score that is equal to 50. _____The population of students who receive help will have a mean science test score that is greater than 50. _____The population of students who receive help will not have a mean science test score that is greater than 50. _____The population of students who receive help will have a mean science test score that is less than 50.

Start with a Person class, and create a multiset to hold pointers to person objects. Define the multiset with the comparePersons function object, so it will be sorted automatically by names of person. Define a half-dozen persons, put them in the multiset, and display its contents. Several of the persons should have the same name, to verify that multiset stores multiple object with the same key. Also allow the user to search a person object by the last name and the first name.

Suppose the demand functions facing a wireless telephone monopolist are QdL=100−200P for each low-demand consumer and QdH=120−200P for each high-demand consumer, where P is the per-minute price in dollars. The marginal cost is $0.02 per minute. Suppose the monopolist offers a menu of two-part tariff plans, with one plan intended for each type of consumer. Suppose too that for any per-minute price PL in the low-demand plan, the fixed fee in the low-demand plan leaves a low-demand consumer with zero surplus; that the number of minutes in the low-demand plan is capped at the number of minutes desired by a low-demand consumer at that plan's per-minute price; and that the high-demand plan has a per-minute price of $0.02 per minute and a fixed fee that leaves the high-demand consumer approximately indifferent between the low- and high-demand plans. Suppose that there are 100 high-demand consumers and 400 low-demand consumers. Will the monopolist's profit be higher when the per-minute price in the low-demand plan is $0.07 or $0.12? Instructions: Round your answers to 2 decimal places as needed.

a. Suppose the monopolist's per-minute price in the low-demand plan is $0.07.

Profit = $.

b. Now suppose the monopolist's per-minute price in the low-demand plan is $0.12.

Profit = $.

Suppose the demand functions facing a wireless telephone monopolist are

          QdL=60−200P

for each low-demand consumer and

          QdH=160−200P

for each high-demand consumer, where P is the per-minute price in dollars. The marginal cost is $0.10 per minute. Suppose the monopolist offers a menu of two-part tariff plans, with one plan intended for each type of consumer. Suppose too that for any per-minute price P_L in the low-demand plan, the fixed fee in the low-demand plan leaves a low-demand consumer with zero surplus; that the number of minutes in the low-demand plan is capped at the number of minutes desired by a low-demand consumer at that plan's per-minute price; and that the high-demand plan has a per-minute price of $0.10 per minute and a fixed fee that leaves the high-demand consumer approximately indifferent between the low- and high-demand plans. Suppose that there are 200 high-demand consumers and 400 low-demand consumers. Will the monopolist's profit be higher when the per-minute price in the low-demand plan is $0.15 or $0.20?

Instructions: Round your answers to 2 decimal places as needed.

a. Suppose the monopolist's per-minute price in the low-demand plan is $0.15.

    Profit = $.

b. Now suppose the monopolist's per-minute price in the low-demand plan is $0.20.

    Profit = $.

Nautical Creations is one of the largest producers of miniature ships in a bottle. An especially complex part of one of the ships needs special production equipment that is not useful for other products. The company purchased this equipment early in 2016 for $200,000. It is now early in 2020, and the manager of the Model Ships Division, Jeri Finley, is thinking about purchasing new equipment to make this part. The current equipment will last for six more years with zero disposal value at that time. It can be sold immediately for $30,000. The following are last year's total manufacturing costs, when production was 7,800 ships:

The cost of the new equipment is $135,000. It has a six year useful life with an estimated disposal value at that time of $50,000. The sales representative selling the new equipment stated, "The new equipment will allow direct labor and variable overhead combined to be reduced by a total of $2.05 per unit." Finley thinks this estimate is accurate, but also knows that a higher quality of direct material will be necessary with the new equipment, costing $0.23 more per unit. Fixed overhead costs will decrease by $4,700.

Finley expects production to be 8,350 ships in each of the next six years. Assume a discount rate of 5%.

REQUIRED

1. What is the difference in net present values if Nautical Creations buys the new equipment instead of keeping their current equipment?

Present Value of $1.00

Present Value of an Annuity of $1.00
