A market research firm used a sample of individuals (32 persons) to rate the purchase potential of a particular product before and after the individuals saw a new television commercial about the product.

Use α=0.05 and the following data to test the hypothesis and comment on the value of the commercial. Please refer to table below and make the following decisions:

1. Set up the null and alternative hypothesis for testing whether there is a difference between situation before and after. Is this independent sample or paired sample? Why?
2. Provide the standard deviation for Sample 1 (Before)
3. Given the hypothesis in (a) would you reject Ho? (Note the significance level of 5%). Please provide short explanation why you reject or do not reject Ho. What is the p-value and what is your conclusion?
4. You would like to reject null hypothesis. At α=2 level of significance, what is your conclusion? Why?
5. What could be the highest confidence of conclusion that purchase potential of a particular product is significantly different before and after the individuals saw a new television commercial about the product?

Using his TightWad(R) database, Stu's MileageMiser has developed a new GPS based service to certify drivers for insurance discounts. He tracks their speeds, locations, and braking activity and delivers reports to insurance companies. January 1, 2009 he had 10,000 paying customers. Of that group, a year later, 9,900 were still customers. He spent $24,000 on programs designed to keep current customers happy and $45,000 on marketing to acquire new customers. His total number of customers on January 1, 2010 was 14,000. His revenue per customer is $55 per year and variable costs before marketing per customer are $5 per year.

e) What is Stu's annual churn rate? What is the retention rate?

Dickinson Limited issued 10-year, 7% debentures with a face value of $2 million on January 1, 2010. The proceeds received were $1.7 million. The discount was amortized on the straight-line basis over the 10-year term. The terms of the debenture stated that the debentures could be redeemed in full at any point before the maturity date, at a price of 105 of the principal. There wan no requirement for a sinking fund. On January 1, 2017, Dickinson inued a mortgage at 101 with a principal of $3 million secured by land and building. The mortgage had a 25-year amortization period, with interest payable at 8%. Upon issuance of the mortgage. Jeremiah used the proceeds to redeem the 7% debentures. Prepare journal entries to record the issuance of the 8% mortgage and the retirement of the 7% debentures.

Tuscin Capital is a hedge fund with an initial investment capital of $100 million. In its first year, the fund earns a return of 30%. The fund charges a 2% management fee based on assets under management at the end of the year and a 20% incentive fee with a hurdle rate of 4% (applicable on the beginning capital position for the year). The ending values of the fund (before fees for the current year) for the first 3 years are given below: 2009 = $130 million 2010 = $110 million 2011 = $140 million Other information: A high water mark provision applies. The incentive fee is based on returns in excess of the hurdle rate and is calculated net of management fee. Investors’ effective return for 2011 is closest to:

Operating cash inflows   Strong Tool Company has been considering purchasing a new lathe to replace a fully depreciated lathe that would otherwise last 5 more years. The new lathe is expected to have a​ 5-year life and depreciation charges of $2,020 in Year​ 1; $3,232 in Year​ 2; $1,919 in Year​ 3; $1,212 in both Year 4 and Year​ 5; and $505

in Year 6. The firm estimates the revenues and expenses​ (excluding depreciation and​ interest) for the new and the old lathes to be as shown in the following table

The firm is subject to a 40% tax rate on ordinary income.

a. Calculate the operating cash inflows associated with each lathe.​ (Note: Be sure to consider the depreciation in year​ 6.)

b. Calculate the operating cash inflows resulting from the proposed lathe replacement.

c. Depict on a time line the incremental operating cash inflows calculated in part b.

a. Calculate the operating cash inflows associated with the new lathe​ below:  ​(Round to the nearest​ dollar.)

Visit the NASDAQ historical prices weblink. First, set the date range to be for exactly 1 year ending on the Monday that this course started. Do this by clicking on the blue dates after “Time Period”. Next, click the “Apply” button. Next, click the link on the right side of the page that says “Download Data” to save the file to your computer.

PLEASE USE DATES: March 16, 2019 - March 15, 2020.
If you use the correct dates the mean should be somewhere between 1200 and 1300. The standard deviation will be between 110 and 120. You should also have 252 rows in the downloaded spreadsheet. If your numbers fit those ranges you are doing it correct

This project will only use the Close values. Assume that the closing prices of the stock form a normally distributed data set. This means that you need to use Excel to find the mean and standard deviation. Then, use those numbers and the methods you learned in sections 6.1-6.3 of the course textbook for normal distributions to answer the questions. Do NOT count the number of data points.

Complete this portion of the assignment within a single Excel file. Show your work or explain how you obtained each of your answers. Answers with no work and no explanation will receive no credit.

1. a) Submit a copy of your dataset along with a file that contains your answers to all of the following questions.

b) What the mean and Standard Deviation (SD) of the Close column in your data set?

c) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points)

2. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at more than $1150? (5 points)
3. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $50 of the mean for that year? (between 50 below and 50 above the mean) (5 points)
4. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than $950 per share. Would this be considered unusal? Use the definition of unusual from the course textbook that is measured as a number of standard deviations (5 points)
5. At what prices would Google have to close in order for it to be considered statistically unusual? You will have a low and high value. Use the definition of unusual from the course textbook that is measured as a number of standard deviations. (5 points)
6. What are Quartile 1, Quartile 2, and Quartile 3 in this data set? Use Excel to find these values. This is the only question that you must answer without using anything about the normal distribution. (5 points)
7. Is the normality assumption that was made at the beginning valid? Why or why not? Hint: Does this distribution have the properties of a normal distribution as described in the course textbook? Real data sets are never perfect, however, it should be close. One option would be to construct a histogram like you did in Project 1 to see if it has the right shape. Something in the range of 10 to 12 classes is a good number. (5 points)

There are also 5 points for miscellaneous items like correct date range, correct mean, correct SD, etc.
