The first three columns in the file $ wa\_wheat $ contain observations on wheat yield in the Western Australian shires Northampton, Chapman Valley, and Mullewa, respectively. There are 48 annual observations for the years 1950 - 1997. The name of the varibale that contains data on the crop yields of the Chapman Valley Shire is called chapman . For the Chapman Valley Shire, consider the four itens below: The tasks performed in this exercise requires the commands discussed in the Notebook Week_5_Econ_103_Lab_Class 2021.ipynb Please study the Notebook before attempting the question. (a) This item consistis of three tasks where Y syands for crop yield of the Chapman Valley Shire: (a.1) Estimate the Linear model Y = ẞ₁ + B₂time + € (a.2) Plot the residuals of the regression (for commands, you can check Section 1 of Week_5_Econ_103_Lab_Class_Part_II.ipynb) (a.3) Test the normality of the residuals using the Jarque-Bera test (for Jarque-Bera test commands, see Section 3 of Week_5_Econ_103_Lab_Class_Part_II.ipynb) (b) This item consistis of three tasks in the same fashion as in the item (a): (b.1) Estimate the Linear-log model Y = = a1a2 log(time) + € (b.2) Plot the residuals of the regression (b.3) Test the normality of the residuals using the Jarque-Bera test (For commands related to the estimation of the Linear-log model, see Section 3 of Week_5_Econ_103_Lab_Class_Part_I. ipynb) (for Jarque-Bera test commands, see Section 3 of Week_5_Econ_103_Lab_Class_Part_II. ipynb) (c) Taking into consideration (i) plots of the fitted equations, (ii) plots of the residuals, (iii) error normality tests, and (iv) values for R², which equation do you think is preferable? (This is a theoretical question, no code needed)

B) has more than one answer .. Thank you

Justify.

The International League of Triple-A minor league baseball consists of 14 teams organized into three divisions: North, South, and West. The data showing the average attendance for the 14 teams in the International League are contained in the Excel Online file below. Also shown are the teams’ records; W denotes the number of games won, L denotes the number of games lost, and PCT is the proportion of games played that were won.

Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor the B antigen is present, the letter O is used.The following table gives the percent of a country's population having each of the eight possible blood types in the sample space. Note that the presence or absence of the Rh antigen is indicated by the symbols + or −, respectively. Blood Types A+ A− B+ B− AB+ AB− O+ O− Percent 35.7 6.1 8.5 1.5 3.4 0.8 37.4 6.6 (a) What is the probability that a person selected at random from the population has a blood type that is type AB given that the person is Rh+? (Round your answer to two decimal places.)(b) What is the probability that a person selected at random from the population has a blood type that is Rh− given that the person is type O? (Round your answer to two decimal places.)

The data below lists states poverty rate, gun deaths per 100,000 people, high school graduation rate and the unemployment rate. Use a 2x2 contingency table for questions 1-3. Use the median to divide each list into 2 groups. 1) Test for independence between poverty rate and gun deaths. 2) Test for independence between high school graduation rate and gun deaths. 3) Test for independence between unemployment and gun deaths. 4) Divide the data into 3 groups by gun deaths: 0-9, 9.1-12 and 12.1-20. Use ANOVA to test the claim that the average poverty rate is the same for the three groups. Be sure to write down the mean and standard deviation for each group. 0-9 9.1-12 12.1-20 n = x = s = n = x = s = n = x = s =
