this homework should be done in 30 minute

Draw a Use Case Diagram based on the following narrative:

A company called Joyful Foods is introducing a system that allows customers to make food orders through their mobile phones. Customers can register new accounts, which include validating credit card information. They can view the menus of various restaurants and they will have the option of checking the restaurants' ratings while doing so. Customers also can rate any restaurant with a rating from 1-10. When they make food orders, they will have the option of paying online. Company staff will have to confirm food orders with the customers by calling them to make sure that the orders are valid. Furthermore, the company hired drivers will be able to view order information to see the location of the customers. Lastly, managers will be able to grant monthly rewards for drivers after checking their performance.

The 2019 annual report for a company includes the following items in its footnotes:
a. The useful life of machinery has been increased from 10 to 15 years.
b. The expected tax rate used to calculate income tax provision has increased from 33% to 38%.
c. The company has started to capitalize small tools purchased beginning in 2006.

For each of the above, determine the effect (higher, lower, or unchanged) of the change on the ratios listed below for the year 2019 and state the reason for the effect (increase(s) and/or decrease(s) in which accounts cause the change):

a. Debt-to-equity
b. Return on assets
c. Cash Flow from operations

A researcher wants to know if the typing speed of a secretary in words per minute is related to the time in hours that it takes to learn the new word processing program. Below is speed versus hours to learn program. Find the standard error of estimate for an average secretary who has a typing speed of 72 words per minute to learn the word processing program.

The SAT is required of most students applying for college admission in the United States. This standardized test has gone through many revisions over the years. In 2005, a new writing section was introduced that includes a direct writing measure in the form of an essay. People argue that female students generally do worse on math tests but better on writing tests. Therefore, the new section may help reduce the usual male lead on the overall average SAT score (The Washington Post, August 30, 2006). The data provided is a sample of 60 students and their writing scores on the SAT from last year. The goal of this case study is to analyze the data and make conclusions about the population SAT scores and the difference between male and female scores.

Note: Use Excel to solve, including screenshots, and directions on how to solve on excel, construct the Null hypothesis too, Include each answer with its question number (1,2,3)

1.Construct the null and the alternative hypotheses to test if females outscore males on writing tests.  

2.Assuming the difference in scores is normally distributed, calculate the value of the test statistic. Do not assume that the population variances are equal.

3.Implement the test at alpha=0.01 and interpret your results.

PoolVac, Inc. manufactures and sells a single product called the “Sting Ray,” which is a patent-protected automatic cleaning device for swimming pools. PoolVac’s Sting Ray faces its closest competitor, Howard Industries, also selling a competing pool cleaner. Using the last 30 quarters of production and cost data, PoolVac wishes to estimate its average variable costs using the following quadratic specification:

AVC = a + bQ + cQ 2

The quarterly data on average variable cost (AVC), and the quantity of Sting Rays produced and sold each quarter (Q) are presented in the data file. PoolVac also wishes to use its sales data for the last 30 quarters to estimate demand for its Sting Ray. Demand for Sting Rays is specified to be a linear function as the following:

Qd = d + eP + fM + gPH in which its price (P), average income for households in the U.S. that have swimming pools (M), and the price of the competing pool cleaner sold by Howard Industries (PH).

1.       Run the appropriate regression to estimate the average variable coast function (avc) for sting rays. Evaluate the statistical significance of the three estimated parameters using a significance level of 5 percent. Be sure to comment on the algebraic signs of the three parameter estimates.

Royal Corporation’s inventory at December 31, 2021, was $126,000 (at cost) based on a physical count of inventory on hand, before any necessary adjustment for the following:

• Merchandise costing $16,000, shipped f.o.b. shipping point from a vendor on December 27, 2021, was received by Royal on January 5, 2022.
• Merchandise costing $46,000 was shipped to a customer f.o.b. shipping point on December 28, 2021, arrived at the customer’s location on January 6, 2022.
• Merchandise costing $22,000 was being held on hand for Jess Company on consignment (i.e., Royal is the consignee).
• Estimated sales returns are 20% of annual sales. Sales revenue was $552,000 with a gross profit ratio of 30%.

What amount should Royal Corporation report as inventory in its December 31, 2021, balance sheet?

ultiple Choice

• $197,280.

• $181,280.

• $227,280.

• $225,405.

Listed below are several transactions that took place during the second and third years of operations for RPG Company.

In addition, you learn that the company incurred advertising costs of $19,000 in year 2, owed the advertising agency $4,400 at the end of year 1, and there were no liabilities at the end of year 3. Also, there were no anticipated bad debts on receivables, and the rent payment was for a two-year period, year 2 and year 3.

Required:
1. Calculate accrual net income for both years.
2. Determine the amount due the advertising agency that would be shown as a liability on RPG’s balance sheet at the end of year 2.
