6.21 LAB: Artwork label (modules) Define the Artist class in Artist.py with a constructor to initialize an artist's information. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. Define the Artwork class in Artwork.py with a constructor to initialize an artwork's information. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Add an import statement to import the Artist class. Add import statements to main.py to import the Artist and Artwork classes. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000

Explain the following well: • GDP deflator • CPI • PPI (WPI) • Inflation (and calculation method) • Linkage (formula) among nominal GDP, real GDP, and GDP deflator • Base year. • How do economists calculate the GDP deflator? Knowing the GDP calculator and Nominal GDP, how do they calculate the real GDP figures? • Explain and distinguish clearly the difference between nominal GDP and real GDP. Offer a clear numerical example to contrast the two better. • In the following table, calculate the nominal and real GDP figures for the three years: Year Quantity of Cars Price of cars Nominal GDP Real GDP (in 2000 dollars) 1999 10 $29,000 2000 12 $27,000 2001 15 $31,000 • How do economists measure the real GDP per capita? How about the growth rate of it?

Question No: 02 This is a subjective question, hence you have to write your answer in the Text-Field given below. SEAT Manufacturing company Ltd reported a net income of Rs 80,000, and depreciation expense and amortization expense of Rs 1500 and Rs 500, respectively for the period 2016. The company also reported the following details during the year: Increase in inventory Rs 2000; Paid cash dividend Rs 2000; Decrease in account receivable Rs 1000; Increase in account payable Rs 1000; Paid long-term debt principal Rs 6000 and paid short-term debt principal Rs 4000; Cash receipt of loan repayments Rs 5000; Increase in income tax payable Rs 3000. (a) Find out what is the net cash flows from operating activities? (b) What is the net cash flows from investing activities?

In an environmental project, a ground source heat pump system will be installed, which will result in an annual fuel savings of $2000/year. The initial investment of the heat pump system is $14 000. The life-time of the heat pump system is 20 years. The annual maintenance cost is $300/year. At the end of the 20 years' life time, the salvage value is $1500. The interest rate is 10%.

Please investigate and comment that how the "annual fuel saving" and its variation will affect the results of

(1) The net present value (NPV) of this investment

(2) The benefit-cost ratio (BCR) of this investment

(3) Internal rate of return (IRR) of this investment

(4) Based on the above NPV, BCR and IRR values, please determine whether this investment is attractive or not?

For example, the "annual fuel saving" varies +/- $0~300 based on the original $2000 /year.

Flower color in buffalo clover is either white or some shade of pink to red. Pollen from a red individual was applied to white flowers in 1999. This seed was germinated in 2000 and four red plants were obtained in the progeny. These four red plants were allowed to self pollinate in summer 2000 to produce the next generation. Populations of progeny from each of the four plants were grown in the greenhouse in spring 2001 and the following data were obtained. Propose a hypothesis and calculate a Chi Square for each plant and the pooled data, and determine if these data fit your hypothesis.

Cross Plant    Red   White

On 1 January 2010, the CB Company purchased for $18000, new vehicle. The delivery cost was a $2000. CB estimated the vehicle will have a residual value of $2000 at the end of its useful life of 6 years. CB Company estimated the vehicle could drive 180,000 km. The vehicle was driven 10,000 km during the year ending at 30 June 2010; 20000 km in the year ending 30 June 2011; 5000 km in the year ending 30 June 2012.

Required: A) Prepare journal entries to record the depreciation for the first 3 years( assume straight line method is used)

B) Prepare the journal entry to record the sale of the vehicle for $3500 on 30 June 2012 using the reducing balance method.

C) Assuming straight line method was used, CB ltd sold the vehicle after one year for $18000. Record the transaction.

Purpose: To ensure that you can get StatCrunch up and running, download and open a data file, create graphical and numeric output, and transfer the output into Word.

1. Open the data file Soda.csv in Excel. The file contains survey responses from 339 adults. Variables are ‘Soda’ = the % of daily fluid intake due to soda, ‘Diet’ = whether or not the individual is on a diet, ‘Gender’ = the gender of the individual, and ‘Age’ = the age in years of the individual.

1. Which of the variables are categorical?

2. Which of the variables are numeric?

3. What are the scales of measurement of the variables?

2. Open the data file StocksTbills1960-2000.csv in StatCrunch. The file contains percent returns for stocks ‘stock’ and US Treasury bills ‘tbill’ for each year from 1960 to 2000.

1. Use StatCrunch to produce a dotplot of ‘tbill’ and paste it

                                                                  here

2. Use StatCrunch to calculate the sample mean of ‘tbill’ and paste the output

9) (CH. 9-2) Is there a difference between the average NBA Championship Final game winning scores of the 1970’s versus the average of the winning scores of the 2000’s? Use a 0.01 significance level to test the claim that there is a difference.

Use the data from problem #9 to construct a 99% confidence interval estimate for the mean of the differences. Does this interval contain zero? Do the results of this problem support the results of problem #9?

• What is the Confidence Interval Estimate:

• Does the interval indicate a difference or not? Explain your answer.

• Do the results of the hypothesis test (from problem #9) and the confidence interval estimate support each other?

Python class

Select a free ebook on gutenberg . org and download the plain text file (utf8). the ebook is (The Devil's Dictionary by Ambrose Bierce)

Write a program that does the following:

• Read in your ebook (any book, any language)
• Break the book into words (look at .split() for strings)
• Make a dictionary of all words and how often they occur: for instance if the word'the'happened 2000 time and the word'a' happened 1940 times word_dict= {'the' : 2000, 'a' :1940}
• Print the dictionary of word frequencies to a file (freqs.txt) with the most frequent at the top and least frequent at the bottom
• No need to submit the book, I will run it on my own files.

Turn in a .py or Google Colab URL

Dictionaries are not easily sortable since they are not ordered like a list. To sort for this assignment use the following template.

import operator

sorted_dict = sorted(my_dict.items(),key=operator.itemgetter(1))
