Chi-square:

Regional restaurants, pressed to reinvent themselves during the Covid pandemic, begin adopting curbside pick-up and custom “to-go” menus. Some of these pick-up deliveries include a personal note of thanks (see below), to affix to their take-out packaging.* A sociologist, interested in assessing whether there’s any relationship between the use of these personal messages and return business during the ensuing three months, draws a random sampling of restaurants from the region. The restaurants are selected to be from low-budget (under $20); moderate budget ($21—40); and high-end dining establishments (above $40) per meal.

The following data accrue from a sampling of some n = 100 restaurants in the region. The cell counts indicate the number of return trips made by the same customers beginning March 30th.

Personal note

Low Budget

Moderate budget

High-end Budget

absent

In a sentence, describe the categorical relationship (you may transform freq’s to percents to help you here).

Is there a strong scientific basis for imputing a causal connection between restaurants’ use of the personal notes and return business? Say in a sentence why or why not.

What fe for the cell (low budget/note attached)?

What fe for the cell (Fine dining/note absent)?

Particle in a box is a model that is often used to look at the spectroscopy of pi electrons in conjugated organic molecules. carotene, a precursor of retinal, a visual pigment found in the retina of the eye, has the formula given below. -carotene contains 11 conjugated double bonds which contribute 22 electrons that are delocalized along the length of the molecular chain. Each level of particle in a box has room for 2 electrons. a. The highest filled energy level is referred to as the HOMO (highest occupied molecular orbital). The quantum number that goes with this level is _____________. b. The lowest unoccupied (no electrons) is referred to as the LUMO (Lowest unoccupied molecular orbital). The quantum number for this level is ____________. c. To calculate the “length” of the box we will use the average bond length of 1.35 A for each carbon-carbon bond. The total length of the box in m is___________________ d. Find an expression for the energy difference between your LUMO and HOMO e. Using the expression in d. calculate the E for an electron moving between the HOMO and LUMO for -carotene. (be very careful about units!..no credit for calculation not done in correct units). f. What part of the electromagnetic spectrum would this transition occur in?

In your opinion, which do you view as more important: 1) health inequalities or 3) health inequities? Explain. Compare and contrast the differences between a person in good health versus a person considered to be in ill health. What factors contribute to a person’s health status? How does cost(s) play a role in a person's ability to obtain "good" health? Consider the ZIP code in which you currently reside. How does the ZIP code impact your personal health? Do you feel your individual behaviors and overall health status reflects your ZIP code? Of the components of socioeconomic status (education, income, occupation, wealth), which do you feel is most important to your overall health status? Why? From a broader perspective of society, should we care about addressing health disparities? Why? What impact do health disparities have on our nation's health care system? Which of the determinants of health (typically researched by scientists and researchers in trying to understand the health differences between populations) do view as most important? Why?

C program and pseudocode for this problem.

A parking garage charges a $2.00 minimum fee to park for up to three hours and additional $0.50 per hour over three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that will calculate and print the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a tabular format, and should calculate and print the total of yesterday's receipts. The program should use the function calculateCharges to determine the charge for each customer. Your output should display the car #, the hours entered and the total charge.

  • List some examples of each quality-related costs - i.e., of prevention, appraisal, and internal and external failure costs - that might result from the production of the parkas.
  • The BA Inc produces 20,000 parkas annually. The quality management program implemented improved average percentage of good parkas produced by 2% each year beginning with 83% good quality parkas in 2005. Only 20% of poor quality parkas can be reworked (and made good). Compute the product yield for each of the 5 years.
  • Assuming a rework cost of $12/parka, determine the manufacturing cost per good parka for each of the 5 years. What do these results imply about the co's quality management program?

HomeGrown Company is a chain of grocery stores that are similar to indoor farmer's markets, providing fresh, local produce, meats, and dairy products to consumers in urban areas. HomeGrown is considering opening several stores in a new city, and has proposals from three contractors (Alpha, Beta, and Gamma companies) who would like to provide buildings for the new stores. The amount of expected revenue from the stores will depend on the design of the contractor. For example, if HomeGrown decides on a more open floor plan, with less shelf space for products, revenue would be lower overall. However, if HomeGrown decides on a very crowded floor plan, it may lose customers who appreciate a more open feel. As the project manager for HomeGrown, you are responsible for deciding which if any of the proposals to accept. HomeGrown's minimum acceptable rate of return is 20%. You receive the following data from the three contractors: Proposal Type of Floor Plan Investment if Selected Residual Value Alpha Very open, like an indoor farmer’s market $1,472,000 $0.00 Beta Standard grocery shelving and layout, minimal aisle space $5,678,900 $0.00 Gamma Mix of open areas and shelving areas $2,325,760 $0.00 You have computed estimates of annual cash flows and average annual income from customers for each of the three contractors' plans. You believe that the annual cash flows will be equal for each of the 10 years for which you are preparing your capital investment analysis. Your conclusions are presented in the following table. Proposal Estimated Average Annual Income Estimated Average (after depreciation) Annual Cash Flow Alpha $302,054 $351,145 Beta $272,019 $489,805 Gamma $571,090 $654,469 You begin by trying to eliminate any proposals that are not yielding the company’s minimum required rate of return of 20%. Complete the following table, and decide whether Alpha, Beta, and/or Gamma should be eliminated because the average rate of return of their project is less than the company's minimum required rate of return. Complete the following table. Enter the average rates of return as percentages rounded to two decimal places. Proposal Average Investment Average Rate of Return Accept or Reject? Estimated Average Annual Income Alpha $ $ % Beta $ $ % Gamma $ $ % You’ve decided to confirm your results from the average rate of return by using the cash payback method. Using the following table, compute the cash payback period of each investment. If required, round the number of years in the cash payback period to a whole number. Proposal Initial Cost Annual Net Cash Inflow Cash Payback Period in Years Alpha $ $ Beta $ $ Gamma $ $ Even though you’re fairly certain that your evaluation and elimination is correct, you would like to compare the three proposals using the net present value method, and get some data about the internal rate of return of the proposals, each of which are expected to generate their respective annual net cash inflows for a period of 10 years. Compute the net present value of each proposal. You may need the following partial table of factors for present value of an annuity of $1. Enter amounts that represent cash outflows as negative numbers using a minus sign. Round the present value of annual net cash flows to the nearest dollar. Present Value of an Annuity of $1 at Compound Interest (Partial Table) Year 10% 20% 1 0.909 0.833 5 3.791 2.991 10 6.145 4.192 Alpha Beta Gamma Annual net cash flow $ $ $ Present value factor Present value of annual net cash flows $ $ $ Less amount to be invested $ $ $ Net present value $ $ $
