We have an array of numbers, and we start at index 0.

At every point, we're allowed to jump from index i to i+3, i+4, or stop where we are.

We'd like to find the maximum possible sum of the numbers we visit.

For example, for the array [14, 28, 79, -87, 29, 34, -7, 65, -11, 91, 32, 27, -5], the answer is 140.

(starting at the 14, we jump 4 spots to 29, then 3 spots to 65, another 3 to 32, then stop. 14 + 29 + 65 + 32 = 140)

What's the maximum possible sum we could visit for this array:

[95, 69, 68, 44, 0, 53, 34, -83, -8, 38, -63, -89, 34, -91, 1, 39, -7, -54, 85, -25, -47, 89, -57, -18, -22, -50, -74, -91, -38, 99, 73, 7, 44, -47, -35, -70, 26, -54, -28, 7, -26, -73, -48, -76, -18, 94, -54, 65, -71, -10, 5, 64, 55, 68, 7, 41, -52, 57, -75, 90, -21, -47, -88, -5, -9, 46, -8, 71, 34, 82, 10, -37, 37, 1, 49, 91, 80, 57, -56, 83, -58, 24, -34, 30, -65, 42, -28, -84, -58, -62, 20, 89, -43, -16, 9, 37, -21, -71, -27, 93, 93, 3, 24, 51, 19, -54, -20, 43, 96, 15, -4, -30, -12, -88, 95, -89, 63, 63, 26, 34, 9, 66, 40, 59, -69, -29, -3, -89, -58, 45, 68, 45, 92, -51, 89, -75, 0, 14, 46, -20, -90, -83, 82, 29, -32, 68, 55, 41, -85, 56, 97, -11, -25, -28, 65, 61, 54, -36, -24, 98, 49, 19, 3, -94, -46, 26, 92, -72, -29, 93, 71, 15, 3, -89, -66, -85, -42, 83, 43, 27, 76, 71, 62, 44, 9, 2, 40, 8, 78, -6, -61, -93, 28, -46, -48, 25, -34, -91, 73, 90, 77, -5, 98, 1, -5, -85, 63, -15, 57, 20, 71, -67, -60, -46, -71, -9, 62, 99, 80, -15, 53, 29, 52, -91, -78, -77, -57, 21, -74, 46, -11, 74, -21, -48, -7, -56, 54, 8, -51, -61, -46, 79, 42, 97, 61, 40, -99, -13, 55, -53, -71, 80, 31, -35, 77, 89, -2, 75, 59, -66, 87, 23, 48, 80, -28, 86, 54, 37, -41, 95, -87, 79, -49, 8, -95, 66, 79, -38, 75, 49, -30, 7, -46, -44, 43, -26, -63, 23, 77, -8, 36, 83, 10, 12, -34, 32, -63, -32, 47, -5, 53, 66, 32, 14, 24, 28, 57, -48, -89, -51, -26, -21, -37, -41, -17, -40, 19, 25, 89, -11, 92, -43, -50, 53, -36, 50, -12, 68, -28, 18, 62, -48, -86, 87, -80, 58, 73, -93, 81, -86, 26, 3, 51, 74, 37, 45, 85, 12, 49, 93, -93, -5, 61, -64, -48, -11, 68, -36, -83, -18, 30, -53, -88, 6, 43, -38, 50, -28, 91, 49, 21, 86, -15, -18, 2, 0, 55, -73, 85, -49, -18, -90, 89, 79, -21, 23, 38, 43, 83, 72, 63, 14, -35, 81, -2, -71, 70, 51, -26, -20, 74, 10, -37, 61, -29, -62, 18, -46, 75, 98, 18, -4, 25, 13, 70, -34, 79, 16, -55, -7, -56, -55, 79, 29, 13, -31, -12, -29, -33, 12, 17, -5, -59, -12, 76, -6, -4, -5, -90, -45, -33, -14, -56, 64, -99, -65, -98, -97, 35, -50, -63, 8, -7, -46, 3, -69, 24, -23, -6, 78, -21, 2, -99, -29, 75, 40, -30, -40, 10, -41, -65, -42, -88, -8, -32, -2, -39, -95, -73, 32, 99, -35, -88, 81, -32, -19, 58, 83, -73, -23, 1, -34, -40, -39, 35, -52, -24, 57, -44, 2]

1.) What are some conditions that a company would recognize revenue over a period of time?

2.) Why are companies required to recognize some revenue over a period of time?

3.) Looking at the principle and process, what are some areas that you think a company could make some errors in recognizing revenue?

To study how social media may influence the products consumers​ buy, researchers collected the opening weekend box office revenue​ (in millions of​ dollars) for 23

recent movies and the social media message rate​ (average number of messages referring to the movie per​ hour). The data are available below. Conduct a complete simple linear regression analysis of the relationship between revenue​ (y) and message rate​ (x).

Q1: Determine the estimate of the standard deviation. s=?????

Q2: What is the test statistic for the​ hypotheses? t=??????

(2 pts) Accrual basis vs. basis – revenue and expense recognition: Suppose Capaldi Corp. provides travel services to customers and noted the following transactions for May 2018:

For each transaction, determine the amount of revenue or (expense), if any, that is recorded under accrual-basis accounting and under cash-basis accounting for May 2018. I have completed transaction a. for you as an example.

(2 pts) Accrual Based Accounting: Prepaid expenses – Depreciation of Fixed Assets. Moving On, Inc. purchases a new moving truck (e.g. ‘equipment’) for $56,000 on October 1^st, 2017. At the time of its purchase, the truck is expected to be used in operations for 4 years and will have no resale or scrap value at the end of its life. Assume Moving On, Inc. uses straight-line depreciation (i.e. the asset depreciates evenly) over the expected life of the truck.

Record the journal entry for the original purchase of the truck that occurs on October 1^st, 2017.

Record the adjusting entry to recognize Depreciation Expense on December 31, 2017.

What will the ending balance of the Accumulated Depreciation account be on December 31, 2018 (Assume the beginning balance of Accumulated Depreciation on January 1^st, 2017 is $0 and Moving On, Inc. has no other assets that depreciate)?

What will the net book value of the truck be on December 31, 2018?

(2 pts) Accrual Based Accounting: Deferred (unearned) revenues. Suppose that on November 29^th, 2017 a customer pays Ood Sphere, Ltd. $2,000 cash in advance for merchandise which will be delivered to the customer on December 5^th.

Record the journal entry for the original purchase of the merchandise that occurs on November 29^th, 2017.

Record the adjusting entry Ood Sphere, Ltd. should record on December 5^th to recognize sales revenue.

Suppose the cost of the merchandise sold (i.e. COGS) is $1,600. When should Ood Sphere, Ltd. record this expense? Why? Briefly explain your answer.

Consider two manufacturing companies of electrical devices with identical business fundamentals. Everything is the same for these two companies (same operations, same economic fundamentals, same suppliers, same customers and same managers). The only difference is in the way the two companies choose to report their
financials.
Company A follows a conservative financial reporting strategy by choosing accounting policies that report the lowest revenue and assets and the highest expense and liabilities.
Company B follows an aggressive financial reporting strategy by choosing accounting policies that report the highest revenue and assets and the lowest expense and liabilities.
Required:
(a) Explain how you can discover information that one company is being conservative in financial reporting and the other company is being aggressive in
financial reporting. You are required to give specific examples that are directly relevant to the context of these two companies being manufacturing companies of electrical devices.
(b) Explain how you could use this newly discovered information that a company is conservative or aggressive in reporting in active investing.

What is the p value for the correlation and what does it mean?

1. The following data refer to the SO2 concentration-time (t), temperature (T), relative humidity (RH), and atmospheric pressure (P) in the last 12 months:

1. Fit a multiple linear regression model to estimate the SO2 concentration in the coming months.

Exercise 1: Thirty nine women with a diagnosis of inoperable or metastatic breast cancer have been followed-up for a number of years, while under continuous treatment with a medication called trastzuzumab. The time (in months) each patient remained in remission was recorded. Remission is is a decrease or disappearance of signs and symptoms of cancer. Below is the data. 50 74 35 39 21 37 27 35 30 35 26 38 34 34 26 41 61 33 33 26 25 41 35 34 44 33 60 61 42 30 80 31 24 49 26 31 28 41 37. 1. Are there any outliers in the sample? If so, indicate their values. 2. Compute the 45-th percentile of the remission time. 3. Find a 97% confidence interval for the average remission time

According to the 14th Annual RBC Homeownership Survey conducted by Ipsos Reid in 2007, most Canadians thought purchasing a home is a good investment. Additionally, there was less concern about interest and mortgage rate hikes than at the same time the year before: 51% were concerned about interest rate increases in 2007 versus 56% in 2006; 43% thought mortgage rates would go up in 2007 versus 70% in 2006. Suppose that these results are based on 1000 randomly selected adult Canadians.

(a) (3 pts) Construct a 93% confidence interval for the proportion of Canadians who were concerned about the mortgage rate increase in 2007.

(b) (3 pts) Construct a 98% confidence interval for the difference in the proportion of Canadians who were concerned about the mortgage rate increase in two years.

(c) (7 pts) Use the p-value method to test if the proportion of Canadians who were concerned about the interest rate has decreased from 2006 to 2007 at the significant level 1%. (d) (3 pts) Interpret the p-value for the test in part (c).
