General Electric recently conducted a study to evaluate filaments in their industrial high intensity bulbs. Investigators recorded the number of weeks each high-intensity bulb would last before failure for three test filaments (Groups 1, 2, and 3) and the standard filament (Group 4). The results are as follows. Using ? = 0.01,

Group       1          2       3        4

1. Write an appropriate ANOVA hypothesis to test the difference in means of the four groups (null and alternative).
2. Read the data into R or R-studio, run an ANOVA model in R and paste the code used as well as the output here. What is the decision based on the ANOVA test? You need to explain what part of the output led you to the conclusion you made.
3. Continue using R: Use the Tukey method to test all pairwise contrasts. Show the R code, output, and explain the results of all the comparisons in complete sentences while referencing the parts/numbers on the output that support your conclusions.

WRITE ALL THE CODE USED THE R or R-STUDIO!

Exercise 6-12 The Flint Inc., a manufacturer of low-sugar, low-sodium, low-cholesterol TV dinners, would like to increase its market share in the Sunbelt. In order to do so, Flint has decided to locate a new factory in the Panama City area. Flint will either buy or lease a site depending upon which is more advantageous. The site location committee has narrowed down the available sites to the following three very similar buildings that will meet their needs.

Building A: Purchase for a cash price of $618,900, useful life 27 years.

Building B: Lease for 27 years with annual lease payments of $71,820 being made at the beginning of the year.

Building C: Purchase for $652,700 cash. This building is larger than needed; however, the excess space can be sublet for 27 years at a net annual rental of $6,430. Rental payments will be received at the end of each year. The Flint Inc. has no aversion to being a landlord.

In which building would you recommend that The Flint Inc. locate, assuming a 12% cost of funds? (Round factor values to 5 decimal places, e.g. 1.25124 and final answer to 0 decimal places, e.g. 458,581.)

The Dean of the Business School at State University would like to test the hypothesis that no difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course. A random sample of eight students who took both courses was selected and their final exam grades for each course are shown below. Assume Population 1 is defined as the Marketing exam scores and Population 2 is defined as the Finance exam scores. Which one of the following statements is​ true?

A.

Because the​ 95% confidence interval includes​ zero, we can conclude that no difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course.

B.

Because the​ 95% confidence interval does include​ zero, we cannot conclude that a difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course.

C.

Because the​ 95% confidence interval includes​ zero, we cannot conclude that no difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course.

D.

Because the​ 95% confidence interval does not include​ zero, we can conclude that a difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course.

Does watching Barney increase altruism in children? Amanda put nine kids in a room where they watched Barney and another nine kids is a quiet room without television. Then the kids filled out a questionnaire that determined their altruism score (which we can assume to be interval). The scores are:

Barney: 43, 55, 63, 57, 77, 65, 84, 73, 66

                Quiet:     67, 55, 74, 63, 56, 33, 45, 53, 47

What kind of Test it is ?

Problems 8-1 Determining balance sheet presentation and preparing journal entries for various receivables transactions (LO 8-1, LO 8-4, LO 8-6)

Aardvark, Inc., began 2017 with the following receivables-related account balances:

Aardvark’s transactions during 2017 include the following:

On April 1, 2017, Aardvark accepted an 8%, 12-month note from Smith Bros. in settlement of a $17,775 past due account.

Aardvark finally ceased all efforts to collect $23,200 from various customers and wrote off their accounts.

Total sales for the year (80% on credit) were $1,765,000. Cash receipts from customers as reported on Aardvark’s cash flow statement were $1,925,000.

Sales for 2017 as reported included $100,000 of merchandise that Jensen, Inc., ordered from Aardvark. Unfortunately, a shipping department error resulted in items valued at $150,000 being shipped to Jensen. Because Jensen believed that it could eventually use the unordered items, it agreed to keep them in exchange for a 10% reduction in their price to cover storage costs. Neither the sales nor the receivable for the extra $50,000 of merchandise were recorded.

On February 1, 2017, Aardvark borrowed $65,000 from Sun Bank and pledged receivables in that amount as collateral for the loan. Interest of 5% was deducted from the cash proceeds. In June, Aardvark repaid the loan.

Aardvark estimates uncollectible accounts using the sales revenue approach. In past years, the bad debt provision was estimated at 1% of gross sales revenue, but a weaker economy in 2017 led management to increase the estimate to 1.5% of gross sales revenue.

On July 1, 2017, Aardvark sold equipment to Zebra Company and received a $100,000 noninterest-bearing note receivable due in three years. The equipment normally sells for $79,383. Assume that the appropriate rate of interest for this transaction is 8%.

25.Your firm (an Australian firm) makes a sale to a Japanese customer.  The sale price is 200 million Japanese Yen payable in exactly three months from today.  The current exchange rate is AUD/JPY = 90 (i.e., 1 Australian Dollar (AUD) is worth 90 Japanese Yen (JPY)). The current interest rates in Australia and Japan are 3% p.a. and 0.5% p.a., respectively.
Given this information, please answer the following questions. Please label your answers according to parts.
(a) Given that Australian Dollar is the domestic currency, what is the direct quote of the exchange rate between Australian Dollar and Japanese Yen ? Please round the final answer to five decimal places.
(b) What is the theoretical current forward exchange rate quoted directly in terms of Australian Dollar (i.e. JPY/AUD) for delivery three months from today ? Show your input to the formula to arrive at the final answer.  Please round the final answer to five decimal places.
(c) How can the firm take advantage of any decreases in the exchange rate and also ensure that it receives at least Australian $2 million ? (Hint: Which derivative instrument can be used to achieve this objective?)
(d) Ignoring the cost of the derivative instrument to be used in part (c), what would be the outcome from hedging if the spot exchange rate in 3 month’s time is (i) AUD/JPY=150 and (ii) AUD/JPY = 50?

27.Your uncle has a big proportion of his life savings deposited in one of the Big Four Australian banks. He read in the newspaper that due to COVID-19, these banks’ profitability has declined significantly as a result of some customers not being able to service their loans and negative economic outlook. He is worried that his deposit in the bank may not be secure and is wondering whether he should withdraw all his deposit from the bank. Knowing that you have just completed this unit, he asked for your advice.
What advice will you provide to your uncle given what you have learned about financial institutions in this unit?

23.Having observed the dramatic rebound of technology stocks from their lows in March 2020, your friend Jake believes that this rally of technology stocks is simply too good to be fundamentally true given the ongoing significant economic impact of COVID-19. Accordingly, he has borrowed 50,000 shares of Cooper Technologies Ltd from his broker and sold them all at the price of $21.08 per share.
Explain the rationale behind Jake’s investment strategy. What is the risk that Jake faces that might keep him awake at night ?

Phonons contribute to the properties of both semiconductors and metals. The energy of a phonon is
about 0.01 eV.
(a) Roughly at what temperature will the phonon energy equal thermal energy? Why is this temperature where the resistivity of a metal starts to increase with increasing temperature? How does the resistivity of a metal then depend on temperature?
(b) Why is the phonon needed for the photo-excited processes in indirect gap material?
