- What does a G01 tell a machine to perform?A study is conducted comparing birth weights (in pounds) of infants born to mothers of various ages. The following data can also be found in the file (a6_q1.xlsx) in the Module "Session 8": Group Information: 1 = "< 20 Years" 2 = "20-29 Years" 3 = "30+ Years" GROUP BIRTHWT 1 8.4 1 7.3 1 9.1 1 7.8 1 8.4 7.5 2 6.3 2 6.9 2 5.4 2 7.1 3 6.9 3 7.1 3 5.7 3 6.5 3 6.6If a model has inputs aligned so that x = the numberof years after 2000, what inputs would be used torepresent 2015 and 2022?
- To test the effectiveness of a job training program on the subsequent wages of workers, we specify the model log(wage) = Bo + Bitrain + Bzeduc + B;exper + u, where train is a binary variable equal to unity if a worker participated in the program. Think of the error term u as containing unobserved worker ability. If less able workers have a greater chance of being selected for the program, and you use an OLS analysis, what can you say about the likely bias in the OLS estimator of B,? (Hint: Refer back to Chapter 3.)A technique for processing jobs on a first-come, first-served basis is known as FIFO why?8)

It shows the detected COVID-19 cases nationwide and in Selangor state in Malaysia after the election. The cases in Sabah have contributed significantly to the increase in Malaysia COVID-19 cases during this period. We want to know whether cases in Selangor have contributed significantly to the whole COVID-19 cases in the country or not in given period. (refer to the uploaded image) i. Determine the regression line equation from the given data. ii. Calculate the coefficient of Pearson correlation from the given data.ii. Conclude the correlation between COVID-19 case data collected for daily new COVID-19 case in Malaysia and Selangor State. From the correlation, do you think the cases in Selangor strongly affect the number of COVID-19 cases in the country in the given 10 days? Please justify your answer.Each year, 50% of the people from City A move to City B, and 30% of the people from City B move to City A. Suppose that both cities have an initial population of 1,000. Calculate the populations of the two cities after 2 years.
